Check Digit Verification of cas no
The CAS Registry Mumber 13974-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,7 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13974-81:
(7*1)+(6*3)+(5*9)+(4*7)+(3*4)+(2*8)+(1*1)=127
127 % 10 = 7
