Check Digit Verification of cas no

The CAS Registry Mumber 33784-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,8 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33784-05:
(7*3)+(6*3)+(5*7)+(4*8)+(3*4)+(2*0)+(1*5)=123
123 % 10 = 3
So 33784-05-3 is a valid CAS Registry Number.
