188983-40-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188983-40-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,8 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 188983-40:
(8*1)+(7*8)+(6*8)+(5*9)+(4*8)+(3*3)+(2*4)+(1*0)=206
206 % 10 = 6
So 188983-40-6 is a valid CAS Registry Number.

Auxiliary-controlled diastereoselection by N-(1-phenylethyl) in Grignard additions to 2-O-benzylglyceraldehyde imines
Veith, Ulrich,Leurs, Stefan,Jaeger, Volker
, p. 329 - 330 (2007/10/03)
Grignard reagents add to 2-O-benzylglyceraldehyde N-(1-phenylethyl)imines in high yield at normal or high pressure (12 kbar); threo vs. erythro selectivity is governed by the (R)- or (S)-1-phenylethyl substituent.
