Check Digit Verification of cas no

The CAS Registry Mumber 3511-27-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,1 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3511-27:
(6*3)+(5*5)+(4*1)+(3*1)+(2*2)+(1*7)=61
61 % 10 = 1
So 3511-27-1 is a valid CAS Registry Number.
