1240503-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240503-36-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,0 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1240503-36:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*0)+(3*3)+(2*3)+(1*6)=99
99 % 10 = 9
So 1240503-36-9 is a valid CAS Registry Number.
