Check Digit Verification of cas no

The CAS Registry Mumber 1254212-23-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,2,1 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1254212-23:
(9*1)+(8*2)+(7*5)+(6*4)+(5*2)+(4*1)+(3*2)+(2*2)+(1*3)=111
111 % 10 = 1
So 1254212-23-1 is a valid CAS Registry Number.
