104223-35-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104223-35-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,2 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104223-35:
(8*1)+(7*0)+(6*4)+(5*2)+(4*2)+(3*3)+(2*3)+(1*5)=70
70 % 10 = 0
So 104223-35-0 is a valid CAS Registry Number.

ASYMMETRIC ALKYLATION AND SULPHENYLATION OF CHIRAL O-SILYLATED IMIDE ENOLATES.
Alexander, Rikki P.,Paterson, Ian
, p. 5339 - 5340 (2007/10/02)
The chiral O-silylated enolates (5) can be alkylated or sulphenylated with high diastereoselectivity (20:1) by 1,3-dithienium fluoroborate or PhSCl.Phenylthioalkylation, in contrast, proceeds with low diastereoselectivity.
