109998-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109998-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,9 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109998-74:
(8*1)+(7*0)+(6*9)+(5*9)+(4*9)+(3*8)+(2*7)+(1*4)=185
185 % 10 = 5
So 109998-74-5 is a valid CAS Registry Number.
