Check Digit Verification of cas no

The CAS Registry Mumber 9043-77-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,4 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 9043-77:
(6*9)+(5*0)+(4*4)+(3*3)+(2*7)+(1*7)=100
100 % 10 = 0
So 9043-77-0 is a valid CAS Registry Number.
