109574-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109574-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,7 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109574-05:
(8*1)+(7*0)+(6*9)+(5*5)+(4*7)+(3*4)+(2*0)+(1*5)=132
132 % 10 = 2
So 109574-05-2 is a valid CAS Registry Number.
