Check Digit Verification of cas no

The CAS Registry Mumber 157458-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,5 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157458-10:
(8*1)+(7*5)+(6*7)+(5*4)+(4*5)+(3*8)+(2*1)+(1*0)=151
151 % 10 = 1
So 157458-10-1 is a valid CAS Registry Number.
