Check Digit Verification of cas no

The CAS Registry Mumber 1282954-32-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,2,9,5 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1282954-32:
(9*1)+(8*2)+(7*8)+(6*2)+(5*9)+(4*5)+(3*4)+(2*3)+(1*2)=178
178 % 10 = 8
So 1282954-32-8 is a valid CAS Registry Number.
