Check Digit Verification of cas no

The CAS Registry Mumber 1639796-08-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,9,7,9 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1639796-08:
(9*1)+(8*6)+(7*3)+(6*9)+(5*7)+(4*9)+(3*6)+(2*0)+(1*8)=229
229 % 10 = 9
So 1639796-08-9 is a valid CAS Registry Number.
