99278-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99278-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,7 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99278-45:
(7*9)+(6*9)+(5*2)+(4*7)+(3*8)+(2*4)+(1*5)=192
192 % 10 = 2
So 99278-45-2 is a valid CAS Registry Number.
