138371-99-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138371-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,7 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138371-99:
(8*1)+(7*3)+(6*8)+(5*3)+(4*7)+(3*1)+(2*9)+(1*9)=150
150 % 10 = 0
So 138371-99-0 is a valid CAS Registry Number.
