Check Digit Verification of cas no

The CAS Registry Mumber 157519-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,1 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 157519-72:
(8*1)+(7*5)+(6*7)+(5*5)+(4*1)+(3*9)+(2*7)+(1*2)=157
157 % 10 = 7
So 157519-72-7 is a valid CAS Registry Number.
