Check Digit Verification of cas no

The CAS Registry Mumber 1293988-30-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,9,8 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1293988-30:
(9*1)+(8*2)+(7*9)+(6*3)+(5*9)+(4*8)+(3*8)+(2*3)+(1*0)=213
213 % 10 = 3
So 1293988-30-3 is a valid CAS Registry Number.
