Check Digit Verification of cas no

The CAS Registry Mumber 1157858-98-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,7,8,5 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1157858-98:
(9*1)+(8*1)+(7*5)+(6*7)+(5*8)+(4*5)+(3*8)+(2*9)+(1*8)=204
204 % 10 = 4
So 1157858-98-4 is a valid CAS Registry Number.
