137994-13-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137994-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,9 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137994-13:
(8*1)+(7*3)+(6*7)+(5*9)+(4*9)+(3*4)+(2*1)+(1*3)=169
169 % 10 = 9
So 137994-13-9 is a valid CAS Registry Number.
