98294-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98294-50-9 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, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98294-50:
(7*9)+(6*8)+(5*2)+(4*9)+(3*4)+(2*5)+(1*0)=179
179 % 10 = 9
So 98294-50-9 is a valid CAS Registry Number.
