Check Digit Verification of cas no
The CAS Registry Mumber 81933-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,3 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81933-74:
(7*8)+(6*1)+(5*9)+(4*3)+(3*3)+(2*7)+(1*4)=146
146 % 10 = 6
So 81933-74-6 is a valid CAS Registry Number.
