109458-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109458-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,5 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109458-99:
(8*1)+(7*0)+(6*9)+(5*4)+(4*5)+(3*8)+(2*9)+(1*9)=153
153 % 10 = 3
So 109458-99-3 is a valid CAS Registry Number.
