1164140-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1164140-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,4,1,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1164140-18:
(9*1)+(8*1)+(7*6)+(6*4)+(5*1)+(4*4)+(3*0)+(2*1)+(1*8)=114
114 % 10 = 4
So 1164140-18-4 is a valid CAS Registry Number.

Diastereoselective alkynylation of glucose-modified imines with terminal alkynes
Mao, Jiangang,Zhang, Pengfei
experimental part, p. 566 - 569 (2009/09/05)
The copper(I)-catalyzed enantioselective alkynylation of aldimines incorporating a 2,3,4,6-tetrakis-O-pivaloyl-d-glucopyranosyl (Piv4Glc) chiral auxiliary with terminal alkynes is reported. The present system provides a versatile tool for the c
