6Check Digit Verification of cas no
The CAS Registry Mumber 71819-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,1 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 71819-57:
(7*7)+(6*1)+(5*8)+(4*1)+(3*9)+(2*5)+(1*7)=143
143 % 10 = 3
So 71819-57-3 is a valid CAS Registry Number.
