Check Digit Verification of cas no

The CAS Registry Mumber 2299-48-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,9 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2299-48:
(6*2)+(5*2)+(4*9)+(3*9)+(2*4)+(1*8)=101
101 % 10 = 1
So 2299-48-1 is a valid CAS Registry Number.
