Check Digit Verification of cas no
The CAS Registry Mumber 61493-63-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,9 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 61493-63:
(7*6)+(6*1)+(5*4)+(4*9)+(3*3)+(2*6)+(1*3)=128
128 % 10 = 8
