Check Digit Verification of cas no

The CAS Registry Mumber 423157-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,3,1,5 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 423157-77:
(8*4)+(7*2)+(6*3)+(5*1)+(4*5)+(3*7)+(2*7)+(1*7)=131
131 % 10 = 1
So 423157-77-1 is a valid CAS Registry Number.
