Check Digit Verification of cas no
The CAS Registry Mumber 27344-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,3,4 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 27344-41:
(7*2)+(6*7)+(5*3)+(4*4)+(3*4)+(2*4)+(1*1)=108
108 % 10 = 8
So 27344-41-8 is a valid CAS Registry Number.
