1402800-34-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1402800-34-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,8,0 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1402800-34:
(9*1)+(8*4)+(7*0)+(6*2)+(5*8)+(4*0)+(3*0)+(2*3)+(1*4)=103
103 % 10 = 3
So 1402800-34-3 is a valid CAS Registry Number.

Chiral iminophosphoranes organocatalyzed asymmetric hydroxylation of 3-substituted oxindoles with oxaziridines

Li, Baocheng,Xu, Zhen-Jiang,Han, Jianwei

, p. 2412 - 2417 (2018)

Enantioselective hydroxylation of N-protected 3-substituted oxindoles has been developed via chiral iminophosphorane catalysis with oxaziridines as oxidants. As such, a variety of optically active 3-substituted-3-hydroxy-2-oxindoles were obtained in excel
