Check Digit Verification of cas no

The CAS Registry Mumber 4743-87-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4743-87:
(6*4)+(5*7)+(4*4)+(3*3)+(2*8)+(1*7)=107
107 % 10 = 7
So 4743-87-7 is a valid CAS Registry Number.
