914080-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 914080-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,4,0,8 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 914080-99:
(8*9)+(7*1)+(6*4)+(5*0)+(4*8)+(3*0)+(2*9)+(1*9)=162
162 % 10 = 2
So 914080-99-2 is a valid CAS Registry Number.
