Check Digit Verification of cas no
The CAS Registry Mumber 116-77-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 116-77:
(5*1)+(4*1)+(3*6)+(2*7)+(1*7)=48
48 % 10 = 8
So 116-77-8 is a valid CAS Registry Number.
