Check Digit Verification of cas no

The CAS Registry Mumber 157690-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157690-40:
(8*1)+(7*5)+(6*7)+(5*6)+(4*9)+(3*0)+(2*4)+(1*0)=159
159 % 10 = 9
So 157690-40-9 is a valid CAS Registry Number.
