Check Digit Verification of cas no

The CAS Registry Mumber 204649-88-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,6,4 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 204649-88:
(8*2)+(7*0)+(6*4)+(5*6)+(4*4)+(3*9)+(2*8)+(1*8)=137
137 % 10 = 7
So 204649-88-7 is a valid CAS Registry Number.
