Check Digit Verification of cas no
The CAS Registry Mumber 28631-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 28631-66:
(7*2)+(6*8)+(5*6)+(4*3)+(3*1)+(2*6)+(1*6)=125
125 % 10 = 5
So 28631-66-5 is a valid CAS Registry Number.
