140136-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140136-66-9 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, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140136-66:
(8*1)+(7*4)+(6*0)+(5*1)+(4*3)+(3*6)+(2*6)+(1*6)=89
89 % 10 = 9
So 140136-66-9 is a valid CAS Registry Number.
