132508-02-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132508-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,0 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132508-02:
(8*1)+(7*3)+(6*2)+(5*5)+(4*0)+(3*8)+(2*0)+(1*2)=92
92 % 10 = 2
So 132508-02-2 is a valid CAS Registry Number.
