329934-89-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 329934-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,9,9,3 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 329934-89:
(8*3)+(7*2)+(6*9)+(5*9)+(4*3)+(3*4)+(2*8)+(1*9)=186
186 % 10 = 6
So 329934-89-6 is a valid CAS Registry Number.
