Check Digit Verification of cas no

The CAS Registry Mumber 324742-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,4,7,4 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 324742-02:
(8*3)+(7*2)+(6*4)+(5*7)+(4*4)+(3*2)+(2*0)+(1*2)=121
121 % 10 = 1
So 324742-02-1 is a valid CAS Registry Number.
