107449-05-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107449-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,4,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 107449-05:
(8*1)+(7*0)+(6*7)+(5*4)+(4*4)+(3*9)+(2*0)+(1*5)=118
118 % 10 = 8
So 107449-05-8 is a valid CAS Registry Number.
