98294-44-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98294-44-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,9 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98294-44:
(7*9)+(6*8)+(5*2)+(4*9)+(3*4)+(2*4)+(1*4)=181
181 % 10 = 1
So 98294-44-1 is a valid CAS Registry Number.
