Check Digit Verification of cas no
The CAS Registry Mumber 940-93-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 940-93:
(5*9)+(4*4)+(3*0)+(2*9)+(1*3)=82
82 % 10 = 2
So 940-93-2 is a valid CAS Registry Number.
