92449-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92449-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,4,4 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92449-43:
(7*9)+(6*2)+(5*4)+(4*4)+(3*9)+(2*4)+(1*3)=149
149 % 10 = 9
So 92449-43-9 is a valid CAS Registry Number.
