140136-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140136-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,3 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140136-29:
(8*1)+(7*4)+(6*0)+(5*1)+(4*3)+(3*6)+(2*2)+(1*9)=84
84 % 10 = 4
So 140136-29-4 is a valid CAS Registry Number.
