Check Digit Verification of cas no
The CAS Registry Mumber 74918-98-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,1 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74918-98:
(7*7)+(6*4)+(5*9)+(4*1)+(3*8)+(2*9)+(1*8)=172
172 % 10 = 2
