Check Digit Verification of cas no

The CAS Registry Mumber 1240501-95-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,0 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1240501-95:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*0)+(3*1)+(2*9)+(1*5)=104
104 % 10 = 4
So 1240501-95-4 is a valid CAS Registry Number.
