124255-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124255-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,5 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 124255-85:
(8*1)+(7*2)+(6*4)+(5*2)+(4*5)+(3*5)+(2*8)+(1*5)=112
112 % 10 = 2
So 124255-85-2 is a valid CAS Registry Number.

5-Alkyl-2-(p-tolylsulfonyl)pyridines by Regioselective Cyano Cycloaddition
Rueffer, Ursula,Breitmaier, Eberhard
, p. 623 - 625 (2007/10/02)
5-Alkyl-2-(p-tolylsulfonyl)pyridines 4 are obtained in good yields at room temperature by cyano cycloaddition of p-toluenesulfonyl cyanide 2 to 2-alkyl-1-ethoxy-1,3-butadienes 1, followed by aromatization of the intermediate dihydropyridine 3 via an
