Check Digit Verification of cas no

The CAS Registry Mumber 148458-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,4,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 148458-33:
(8*1)+(7*4)+(6*8)+(5*4)+(4*5)+(3*8)+(2*3)+(1*3)=157
157 % 10 = 7
So 148458-33-7 is a valid CAS Registry Number.
