98442-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98442-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,4 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98442-43:
(7*9)+(6*8)+(5*4)+(4*4)+(3*2)+(2*4)+(1*3)=164
164 % 10 = 4
So 98442-43-4 is a valid CAS Registry Number.
