Check Digit Verification of cas no

The CAS Registry Mumber 958447-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,8,4,4 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 958447-75:
(8*9)+(7*5)+(6*8)+(5*4)+(4*4)+(3*7)+(2*7)+(1*5)=231
231 % 10 = 1
So 958447-75-1 is a valid CAS Registry Number.
