Check Digit Verification of cas no

The CAS Registry Mumber 1192110-03-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,1,1 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1192110-03:
(9*1)+(8*1)+(7*9)+(6*2)+(5*1)+(4*1)+(3*0)+(2*0)+(1*3)=104
104 % 10 = 4
So 1192110-03-4 is a valid CAS Registry Number.

Stereoselective synthesis of isoindolinones and tert-butyl sulfoxides

Kaw?cki, Robert,Stańczyk, Wojciech,Jaglińska, Agnieszka

, p. 578 - 584 (2017/12/28)

A reaction of Grignard reagents with an optically pure N-sulfinylimine derived from methyl 2-formylbenzoate yields enantioenriched isoindolinones and tert-butyl sulfoxides. The products are formed by the addition of the nucleophile to N-sulfinylimine followed by cyclization to form N-tert-butylsulfinylisoindolinone, which readily undergoes substitution with a second equivalent of Grignard reagent. The reaction can be carried out in dichloromethane at room temperature or at elevated temperatures without any loss of stereoselectivity. The use of nucleophiles other than Grignard reagents has also been investigated.

Aryl tert-butyl sulfoxide-promoted highly enantioselective addition of allyltrichlorosilane to aldehydes

Wang, Peng,Chen, Junmin,Cun, Linfeng,Deng, Jingen,Zhu, Jin,Liao, Jian

experimental part, p. 3741 - 3747 (2009/10/24)

A series of enantiomerically pure mono- and bis-aryl tert-butyl sulfoxides were synthesised to promote the enantioselective allylation of aldehydes with allyltrichlorosilane. Moderate to good yields and modest to high enantioselectivities were achieved. The absence of nonlinear effect, spacer effect, promoter loading and concentration effect indicate that only one molecule of aryl tert-butyl sulfoxide is involved in the stereodetermining step.
