Check Digit Verification of cas no

The CAS Registry Mumber 942129-14-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,1,2 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 942129-14:
(8*9)+(7*4)+(6*2)+(5*1)+(4*2)+(3*9)+(2*1)+(1*4)=158
158 % 10 = 8
So 942129-14-8 is a valid CAS Registry Number.

2-Alkenoyl pyridine N-oxides, highly efficient dienophiles for the enantioselective Cu(II)-bis(oxazoline) catalyzed diels - Alder reaction

Barroso, Santiago,Blay, Gonzalo,Pedro, Jose R.

, p. 1983 - 1986 (2007)

2-Alkenoyl pyridine N-oxides are introduced as a new kind of efficient dienophiles for the Cu(II)-bis(oxazoline) (BOX) catalyzed enantioselective Diels-Alder reaction affording higher reactivity and enantioselectivity (ee's up to 96%) than the correspondi

Enantioselective Friedel-Crafts alkylation of pyrroles catalyzed by PYBOX-DIPH-Zn(II) complexes

Singh, Pradeep K.,Singh, Vinod K.

supporting information; experimental part, p. 80 - 83 (2010/03/03)

Chemical Equation Presented A highly enantioselective Friedel-Crafts alkylation of pyrroles with 2-enoylpyridine 2-oxides catalyzed by chiral PYBOX-DIPH-Zn(II) complexes has been developed. The catalyst offers substantial substrate scope and furnished alkylated pyrroles in excellent yields (up to 99%) and enantioselectivities (up to >99% ee).
