191927-39-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191927-39-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,9,2 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 191927-39:
(8*1)+(7*9)+(6*1)+(5*9)+(4*2)+(3*7)+(2*3)+(1*9)=166
166 % 10 = 6
So 191927-39-6 is a valid CAS Registry Number.

Asymmetric synthesis of 1,3-dialkyl-substituted carbon chains of any stereochemical configuration by an iterable process
Myers, Andrew G.,Yang, Bryant H.,Chen, Hou,Kopecky, David J.
, p. 457 - 459 (2007/10/03)
A highly practical, iterable method for the preparation of 1,3,5,n(odd)-polyalkyl-substituted carbon chains based upon the asymmetric alkylation of pseudoephedrine amide enolates is described.
