Check Digit Verification of cas no
The CAS Registry Mumber 80-22-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80-22:
(4*8)+(3*0)+(2*2)+(1*2)=38
38 % 10 = 8
So 80-22-8 is a valid CAS Registry Number.
