Check Digit Verification of cas no

The CAS Registry Mumber 1243585-35-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,5,8 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1243585-35:
(9*1)+(8*2)+(7*4)+(6*3)+(5*5)+(4*8)+(3*5)+(2*3)+(1*5)=154
154 % 10 = 4
So 1243585-35-4 is a valid CAS Registry Number.
