Check Digit Verification of cas no
The CAS Registry Mumber 3267-41-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,6 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3267-41:
(6*3)+(5*2)+(4*6)+(3*7)+(2*4)+(1*1)=82
82 % 10 = 2
So 3267-41-2 is a valid CAS Registry Number.
