Check Digit Verification of cas no

The CAS Registry Mumber 2881-84-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,8 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2881-84:
(6*2)+(5*8)+(4*8)+(3*1)+(2*8)+(1*4)=107
107 % 10 = 7
So 2881-84-7 is a valid CAS Registry Number.
