Check Digit Verification of cas no
The CAS Registry Mumber 111545-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,5,4 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111545-49:
(8*1)+(7*1)+(6*1)+(5*5)+(4*4)+(3*5)+(2*4)+(1*9)=94
94 % 10 = 4
So 111545-49-4 is a valid CAS Registry Number.
