Check Digit Verification of cas no

The CAS Registry Mumber 1246869-76-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,8,6 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1246869-76:
(9*1)+(8*2)+(7*4)+(6*6)+(5*8)+(4*6)+(3*9)+(2*7)+(1*6)=200
200 % 10 = 0
So 1246869-76-0 is a valid CAS Registry Number.
