140174-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140174-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,7 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140174-90:
(8*1)+(7*4)+(6*0)+(5*1)+(4*7)+(3*4)+(2*9)+(1*0)=99
99 % 10 = 9
So 140174-90-9 is a valid CAS Registry Number.
