140435-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140435-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,3 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140435-91:
(8*1)+(7*4)+(6*0)+(5*4)+(4*3)+(3*5)+(2*9)+(1*1)=102
102 % 10 = 2
So 140435-91-2 is a valid CAS Registry Number.
