Check Digit Verification of cas no
The CAS Registry Mumber 51369-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,3,6 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51369-99:
(7*5)+(6*1)+(5*3)+(4*6)+(3*9)+(2*9)+(1*9)=134
134 % 10 = 4
So 51369-99-4 is a valid CAS Registry Number.

, (2008/06/13)
In one of its embodiments this invention provides smoking compositions which contain a novel unsymmetrical 2,5-diacylpyrazine flavorant additive as illustrated by 1-[5-(1-propanoyl)-2-pyrazinyl]-2--methyl-1-propanone: Under normal cigarette smoking conditions, the 2,5-diacylpyrazine additive volatilizes and enhances the flavor and aroma of the mainstream and sidestream smoke.
