140840-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140840-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,4 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140840-42:
(8*1)+(7*4)+(6*0)+(5*8)+(4*4)+(3*0)+(2*4)+(1*2)=102
102 % 10 = 2
So 140840-42-2 is a valid CAS Registry Number.
