154140-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154140-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,1,4 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 154140-99:
(8*1)+(7*5)+(6*4)+(5*1)+(4*4)+(3*0)+(2*9)+(1*9)=115
115 % 10 = 5
So 154140-99-5 is a valid CAS Registry Number.
