Since it is a 12 digit number, there are chances of mistakes in day to day life. However, ISO has introduced the check digit, using which one can identify the correctness of the ISIN number. The check digit helps in identifying the errors in previous 11 bits.
Helen Adams Keller (June 27, 1880 â June 1, 1968) was an American author, political activist, and lecturer.
Helen Keller was as interested in the welfare of blind persons in other countries as she was for those in her own country; conditions in poor and war-ravaged nations were of particular concern. Helen's ability to empathize with the individual citizen in need as well as her ability to work with world leaders to shape global policy on vision loss made her a supremely effective ambassador for disabled persons worldwide.
