Check Digit Verification of cas no
The CAS Registry Mumber 157332-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,3,3 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157332-81:
(8*1)+(7*5)+(6*7)+(5*3)+(4*3)+(3*2)+(2*8)+(1*1)=135
135 % 10 = 5
So 157332-81-5 is a valid CAS Registry Number.
