Check Digit Verification of cas no

The CAS Registry Mumber 2749-25-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2749-25:
(6*2)+(5*7)+(4*4)+(3*9)+(2*2)+(1*5)=99
99 % 10 = 9
So 2749-25-9 is a valid CAS Registry Number.
