Check Digit Verification of cas no

The CAS Registry Mumber 4087-22-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,8 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4087-22:
(6*4)+(5*0)+(4*8)+(3*7)+(2*2)+(1*2)=83
83 % 10 = 3
So 4087-22-3 is a valid CAS Registry Number.
