1240262-27-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240262-27-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,2,6 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1240262-27:
(9*1)+(8*2)+(7*4)+(6*0)+(5*2)+(4*6)+(3*2)+(2*2)+(1*7)=104
104 % 10 = 4
So 1240262-27-4 is a valid CAS Registry Number.
