Check Digit Verification of cas no

The CAS Registry Mumber 4723-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4723-71:
(6*4)+(5*7)+(4*2)+(3*3)+(2*7)+(1*1)=91
91 % 10 = 1
So 4723-71-1 is a valid CAS Registry Number.
