109914-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109914-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,1 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109914-98:
(8*1)+(7*0)+(6*9)+(5*9)+(4*1)+(3*4)+(2*9)+(1*8)=149
149 % 10 = 9
So 109914-98-9 is a valid CAS Registry Number.
