128329-63-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128329-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,2 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128329-63:
(8*1)+(7*2)+(6*8)+(5*3)+(4*2)+(3*9)+(2*6)+(1*3)=135
135 % 10 = 5
So 128329-63-5 is a valid CAS Registry Number.
