1262957-11-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262957-11-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,9,5 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1262957-11:
(9*1)+(8*2)+(7*6)+(6*2)+(5*9)+(4*5)+(3*7)+(2*1)+(1*1)=168
168 % 10 = 8
So 1262957-11-8 is a valid CAS Registry Number.

A new C2-symmetric azolium compound for Cu-catalyzed asymmetric conjugate addition of R2Zn to cyclic enone
Harano, Ayako,Sakaguchi, Satoshi
experimental part, p. 61 - 67 (2011/02/16)
A new chiral N-heterocyclic carbene (NHC) ligand was designed. Thus, an efficient synthetic route to C2-symmetric bis(hydroxyamide)- functionalized benzimidazolium salts from chiral β-amino alcohols was developed. The combination of Cu(OTf)sub
