Check Digit Verification of cas no

The CAS Registry Mumber 2872-48-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,7 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2872-48:
(6*2)+(5*8)+(4*7)+(3*2)+(2*4)+(1*8)=102
102 % 10 = 2
So 2872-48-2 is a valid CAS Registry Number.
