158817-23-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 158817-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,8,1 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 158817-23:
(8*1)+(7*5)+(6*8)+(5*8)+(4*1)+(3*7)+(2*2)+(1*3)=163
163 % 10 = 3
So 158817-23-3 is a valid CAS Registry Number.
