156875-72-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156875-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,8,7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 156875-72:
(8*1)+(7*5)+(6*6)+(5*8)+(4*7)+(3*5)+(2*7)+(1*2)=178
178 % 10 = 8
So 156875-72-8 is a valid CAS Registry Number.

Design of optically active selenium reagents having a chiral tertiary amino group and their application to asymmetric inter- and intramolecular oxyselenenylations

Fujita, Ken-ichi,Murata, Kazuhisa,Iwaoka, Michio,Tomoda, Shuji

, p. 2029 - 2048 (2007/10/03)

A new class of chiral selenium reagents 4-7 was synthesized on the basis of the concept that the strong intramolecular interaction between an electrophilic selenium and an optically modified tertiary amine (Se··N interaction) would induce asymmetric induc

Fujita, Ken-ichi,Iwaoka, Michio,Tomoda, Shuji

, p. 923 - 926 (2007/10/02)

Optically active diaryl diselenides carrying C2 symmetrical chiral pyrrolidines are synthesized by the condensation between 2,2'-diselenobis(benzyl chloride) derivatives and chiral pyrrolidines and are applied to methoxyselenylation of trans-ol
