138834-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138834-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,3 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138834-99:
(8*1)+(7*3)+(6*8)+(5*8)+(4*3)+(3*4)+(2*9)+(1*9)=168
168 % 10 = 8
So 138834-99-8 is a valid CAS Registry Number.

Optically Active Quaternary Carbon Centers from the Photoaddition of Chromium-Alkoxycarbene Complexes and Optically Active Thiazolines

Thompson, Douglas K.,Suzuki, Naoki,Hegedus, Louis S.,Satoh, Yoshitaka

, p. 1461 - 1467 (1992)

The photolytic reaction of chromium-alkoxycarbene complexes with valine-derived, optically active thiazolines produced optically active β-lactam penam derivatives in fair to good yield and with high diastereoselectivity.In most cases alcoholysis of the β-lactam followed by solvolysis of the thiazolidine ring produced optically active quaternary centers having carbon substituents in four different oxidation states - alkane, alkoxy, aldehyde, and ester.The absolute configuration of the stereogenic center could be inverted by a sequence of redox manipulations of the ester and aldehyde group, making either enantiomer available from the same precursor.
