Check Digit Verification of cas no

The CAS Registry Mumber 22395-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,9 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22395-01:
(7*2)+(6*2)+(5*3)+(4*9)+(3*5)+(2*0)+(1*1)=93
93 % 10 = 3
So 22395-01-3 is a valid CAS Registry Number.
