Check Digit Verification of cas no
The CAS Registry Mumber 117-88-4 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 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117-88:
(5*1)+(4*1)+(3*7)+(2*8)+(1*8)=54
54 % 10 = 4
So 117-88-4 is a valid CAS Registry Number.
