299437-30-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 299437-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,4,3 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 299437-30:
(8*2)+(7*9)+(6*9)+(5*4)+(4*3)+(3*7)+(2*3)+(1*0)=192
192 % 10 = 2
So 299437-30-2 is a valid CAS Registry Number.

Use of optically active cyclic N,N-dialkyl aminals in asymmetric induction.
Jung,Huang
, p. 2659 - 2661 (2007/10/03)
[reaction: see text]Cyclization of the optically active ketone N,N-dialkyl aminals A affords the diastereomer B as the major product with diastereoselectivities ranging from nearly 1:1 to essentially 100:0 depending on the cyclization studied.
