Check Digit Verification of cas no

The CAS Registry Mumber 1840-68-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,4 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1840-68:
(6*1)+(5*8)+(4*4)+(3*0)+(2*6)+(1*8)=82
82 % 10 = 2
So 1840-68-2 is a valid CAS Registry Number.
