140709-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140709-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,7,0 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140709-93:
(8*1)+(7*4)+(6*0)+(5*7)+(4*0)+(3*9)+(2*9)+(1*3)=119
119 % 10 = 9
So 140709-93-9 is a valid CAS Registry Number.
