Check Digit Verification of cas no
The CAS Registry Mumber 128-79-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128-79:
(5*1)+(4*2)+(3*8)+(2*7)+(1*9)=60
60 % 10 = 0
So 128-79-0 is a valid CAS Registry Number.
