99845-70-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99845-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,4 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99845-70:
(7*9)+(6*9)+(5*8)+(4*4)+(3*5)+(2*7)+(1*0)=202
202 % 10 = 2
So 99845-70-2 is a valid CAS Registry Number.

Oxidative Ring-Opening of 1H-Pyrazol-5-amines and Its Application in Constructing Pyrazolo–Pyrrolo–Pyrazine Scaffolds by Domino Cyclization

Bao, Xiaoguang,Fu, Rui,Gao, Ke,Jin, Feng,Pan, Lei,Zhou, Shaofang

supporting information, p. 2956 - 2961 (2020/05/16)

Herein, an oxidative ring-opening of 1H-pyrazol-5-amines to form 3-diazenylacrylonitrile derivatives under mild and transition-metal-free conditions is described. In addition, the nucleophilic addition of deprotonated 1H-pyrrole-2-carbaldehydes to the vinyl moiety of the yielded 3-diazenylacrylonitriles could trigger domino cyclization to afford the 3H-pyrazolo[3,4-e]pyrrolo[1,2-a]pyrazine derivatives. Computational studies suggest that the oxidation of 1H-pyrazol-5-amines in the presence of PhIO is through the formation of a hydroxylamine intermediate followed by elimination of H2O to result in the ring-opening product. The detailed domino cyclization pathway leading to the pyrazolo–pyrrolo–pyrazine scaffolds is revealed.
