Check Digit Verification of cas no

The CAS Registry Mumber 1256554-12-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,5,5 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1256554-12:
(9*1)+(8*2)+(7*5)+(6*6)+(5*5)+(4*5)+(3*4)+(2*1)+(1*2)=157
157 % 10 = 7
So 1256554-12-7 is a valid CAS Registry Number.

Catalytic effect and recyclability of imidazolium-tagged bis(oxazoline) based catalysts in asymmetric Henry reactions

Zhou, Zhi-Ming,Li, Zhi-Huai,Hao, Xiao-Yan,Zhang, Jun,Dong, Xiao,Liu, Ying-Qiang,Sun, Wen-Wen,Cao, Dan,Wang, Jin-Liang

, p. 2113 - 2118 (2012)

Functional imidazolium ionic liquids have been developed as a new class of versatile catalysts. C2-symmetric imidazolium-tagged bis(oxazoline) ligands were prepared, and the anions of the ligands were altered. The catalysts based on the new lig

Noncovalent immobilization of ionic-tagged box-Cu(OAc)2 complex and its application in asymmetric henry reaction

Li, Zhi-Huai,Zhou, Zhi-Ming,Hao, Xiao-Yan,Zhang, Jun,Dong, Xiao,Liu, Ying-Qiang

, p. 1092 - 1095 (2013/02/23)

Immobilized Cu(OAc)2-bis(oxazolines) via hydrogen bonding by SBA-15 was applied to asymmetric Henry reaction, and good enantioselectivities were obtained (up to 83% ee) between 2-methoxybenzaldehyde and CH 3NO2 in isopropy

Enantioselective Henry reaction catalyzed by C2-symmetric chiral diamine-copper(II) complex

Selvakumar, Sermadurai,Sivasankaran, Dhanasekaran,Singh, Vinod K.

supporting information; experimental part, p. 3156 - 3162 (2011/02/25)

A copper(II) complex of C2-symmetric diamine has been proved to be an efficient catalyst for the enantioselective Henry reaction between nitroalkanes and various aldehydes to provide β-hydroxy nitroalkanes in high yields (up to 97%), moderate diastereoselectivities (up to 71:29) and excellent enantiomeric excesses (up to 96%). The chiral nitroaldol adduct obtained has been further converted into chiral aziridine in few steps.
