Check Digit Verification of cas no
The CAS Registry Mumber 5329-12-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,2 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5329-12:
(6*5)+(5*3)+(4*2)+(3*9)+(2*1)+(1*2)=84
84 % 10 = 4
So 5329-12-4 is a valid CAS Registry Number.
