Check Digit Verification of cas no

The CAS Registry Mumber 4737-18-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,3 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4737-18:
(6*4)+(5*7)+(4*3)+(3*7)+(2*1)+(1*8)=102
102 % 10 = 2
So 4737-18-2 is a valid CAS Registry Number.
