Check Digit Verification of cas no
The CAS Registry Mumber 344344-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,3,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 344344-45:
(8*3)+(7*4)+(6*4)+(5*3)+(4*4)+(3*4)+(2*4)+(1*5)=132
132 % 10 = 2
So 344344-45-2 is a valid CAS Registry Number.
