Check Digit Verification of cas no

The CAS Registry Mumber 142273-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,7 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142273-57:
(8*1)+(7*4)+(6*2)+(5*2)+(4*7)+(3*3)+(2*5)+(1*7)=112
112 % 10 = 2
So 142273-57-2 is a valid CAS Registry Number.
