Check Digit Verification of cas no

The CAS Registry Mumber 33622-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,2 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33622-41:
(7*3)+(6*3)+(5*6)+(4*2)+(3*2)+(2*4)+(1*1)=92
92 % 10 = 2
So 33622-41-2 is a valid CAS Registry Number.
