Check Digit Verification of cas no

The CAS Registry Mumber 1723-72-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,2 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1723-72:
(6*1)+(5*7)+(4*2)+(3*3)+(2*7)+(1*2)=74
74 % 10 = 4
So 1723-72-4 is a valid CAS Registry Number.
