623931-74-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 623931-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,9,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 623931-74:
(8*6)+(7*2)+(6*3)+(5*9)+(4*3)+(3*1)+(2*7)+(1*4)=158
158 % 10 = 8
So 623931-74-8 is a valid CAS Registry Number.
