Check Digit Verification of cas no
The CAS Registry Mumber 615575-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,5,5,7 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 615575-22:
(8*6)+(7*1)+(6*5)+(5*5)+(4*7)+(3*5)+(2*2)+(1*2)=159
159 % 10 = 9
So 615575-22-9 is a valid CAS Registry Number.
