Check Digit Verification of cas no

The CAS Registry Mumber 1177-51-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1177-51:
(6*1)+(5*1)+(4*7)+(3*7)+(2*5)+(1*1)=71
71 % 10 = 1
So 1177-51-1 is a valid CAS Registry Number.
