1225161-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1225161-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,5,1,6 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1225161-40:
(9*1)+(8*2)+(7*2)+(6*5)+(5*1)+(4*6)+(3*1)+(2*4)+(1*0)=109
109 % 10 = 9
So 1225161-40-9 is a valid CAS Registry Number.
