Check Digit Verification of cas no
The CAS Registry Mumber 42491-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,9 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42491-95:
(7*4)+(6*2)+(5*4)+(4*9)+(3*1)+(2*9)+(1*5)=122
122 % 10 = 2
So 42491-95-2 is a valid CAS Registry Number.
