Check Digit Verification of cas no

The CAS Registry Mumber 1204655-61-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,6,5 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1204655-61:
(9*1)+(8*2)+(7*0)+(6*4)+(5*6)+(4*5)+(3*5)+(2*6)+(1*1)=127
127 % 10 = 7
So 1204655-61-7 is a valid CAS Registry Number.
