Check Digit Verification of cas no
The CAS Registry Mumber 1217315-74-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,3,1 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1217315-74:
(9*1)+(8*2)+(7*1)+(6*7)+(5*3)+(4*1)+(3*5)+(2*7)+(1*4)=126
126 % 10 = 6
So 1217315-74-6 is a valid CAS Registry Number.

Nitropyridines. 7*. Synthesis of nitropyridines from nitro-malonic dialdehyde
Sagitullina,Garkushenko,Silina,Sagitullin
experimental part, p. 948 - 951 (2010/03/26)
Cyclocondensation of sodium nitromalone dialdehyde with different enamines gave 3-acetyl(benzoyl, cyano, cyclopropanoyl, carbethoxy)-2-methyl(phenyl)-5- nitropyridines. With the aim of increasing the yield of pyridines we have activated the nitromalonic d
