Check Digit Verification of cas no

The CAS Registry Mumber 2757-95-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2757-95:
(6*2)+(5*7)+(4*5)+(3*7)+(2*9)+(1*5)=111
111 % 10 = 1
So 2757-95-1 is a valid CAS Registry Number.
