Check Digit Verification of cas no

The CAS Registry Mumber 1001652-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,1,6,5 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1001652-40:
(9*1)+(8*0)+(7*0)+(6*1)+(5*6)+(4*5)+(3*2)+(2*4)+(1*0)=79
79 % 10 = 9
So 1001652-40-9 is a valid CAS Registry Number.
