Check Digit Verification of cas no

The CAS Registry Mumber 157142-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,4 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157142-50:
(8*1)+(7*5)+(6*7)+(5*1)+(4*4)+(3*2)+(2*5)+(1*0)=122
122 % 10 = 2
So 157142-50-2 is a valid CAS Registry Number.
