138325-29-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138325-29-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,2 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138325-29:
(8*1)+(7*3)+(6*8)+(5*3)+(4*2)+(3*5)+(2*2)+(1*9)=128
128 % 10 = 8
So 138325-29-8 is a valid CAS Registry Number.
