Check Digit Verification of cas no

The CAS Registry Mumber 142913-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,1 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142913-77:
(8*1)+(7*4)+(6*2)+(5*9)+(4*1)+(3*3)+(2*7)+(1*7)=127
127 % 10 = 7
So 142913-77-7 is a valid CAS Registry Number.
