Check Digit Verification of cas no

The CAS Registry Mumber 3973-22-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,7 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3973-22:
(6*3)+(5*9)+(4*7)+(3*3)+(2*2)+(1*2)=106
106 % 10 = 6
So 3973-22-6 is a valid CAS Registry Number.
