138831-29-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138831-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,3 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138831-29:
(8*1)+(7*3)+(6*8)+(5*8)+(4*3)+(3*1)+(2*2)+(1*9)=145
145 % 10 = 5
So 138831-29-5 is a valid CAS Registry Number.
