1452776-83-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1452776-83-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,2,7,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1452776-83:
(9*1)+(8*4)+(7*5)+(6*2)+(5*7)+(4*7)+(3*6)+(2*8)+(1*3)=188
188 % 10 = 8
So 1452776-83-8 is a valid CAS Registry Number.

Regioselective sulfonylation and N- to O-sulfonyl migration of quinazolin-4(3H)-ones and analogous thienopyrimidin-4(3H)-ones

Mertens, Matthias D.,Pietsch, Markus,Schnakenburg, Gregor,Guetschow, Michael

, p. 8966 - 8979 (2013/10/08)

The sulfonylation of quinazolin-4(3H)-ones and related tetrahydrobenzothieno[2,3-d]pyrimidin-4(3H)-ones with mesyl, tosyl, and p-cyanobenzenesulfonyl chloride was studied. A hydrogen substituent at 2-position directed the sulfonyl group to the N-3 position, while alkylsulfanyl or amino substituents led to sulfonylation of the carbonyl oxygen. The latter effect was attributed to steric influence and the positive mesomeric effect of the 2-substituent. An access to N-sulfonylated 2-substituted regioisomers was established. An unexpected 1,3-sulfonyl migration was observed and further analyzed. This process occurred as an intramolecular N- to O-shift as verified by kinetic and crossover experiments.
