Check Digit Verification of cas no
The CAS Registry Mumber 117-22-6 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, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117-22:
(5*1)+(4*1)+(3*7)+(2*2)+(1*2)=36
36 % 10 = 6
So 117-22-6 is a valid CAS Registry Number.
