Check Digit Verification of cas no

The CAS Registry Mumber 1276540-08-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,5,4 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1276540-08:
(9*1)+(8*2)+(7*7)+(6*6)+(5*5)+(4*4)+(3*0)+(2*0)+(1*8)=159
159 % 10 = 9
So 1276540-08-9 is a valid CAS Registry Number.
