Check Digit Verification of cas no

The CAS Registry Mumber 1257204-48-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,2,0 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1257204-48:
(9*1)+(8*2)+(7*5)+(6*7)+(5*2)+(4*0)+(3*4)+(2*4)+(1*8)=140
140 % 10 = 0
So 1257204-48-0 is a valid CAS Registry Number.

DECARBOXYLATIVE CROSS-COUPLING AND APPLICATIONS THEREOF

-

Page/Page column 44, (2015/12/09)

Methods described herein enable the production of numerous molecular species through decarboxylative cross-coupling via use of photoredox and transition metal catalysts. For example, methods described herein enable the production of numerous molecular species through decarboxylative cross-coupling via use of photoredox and transition metal catalysts. A method described herein, in some embodiments, comprises providing a reaction mixture including a photoredox catalyst, a transition metal catalyst, a coupling partner and a substrate having a carboxyl group. The reaction mixture is irradiated with a radiation source resulting in cross-coupling of the substrate and coupling partner via a mechanism including decarboxylation, wherein the coupling partner is selected from the group consisting of a substituted aromatic compound and a substituted aliphatic compound.

In situ trapping of Boc-2-pyrrolidinylmethylzinc iodide with aryl iodides: Direct synthesis of 2-benzylpyrrolidines

Massah, Ahmad Reza,Ross, Andrew J.,Jackson, Richard F. W.

, p. 8275 - 8278 (2011/03/18)

Addition of (S)-(+)-tert-butyl 2-(iodomethyl)pyrrolidine-1-carboxylate to activated zinc, aryl halides, and a catalyst derived from Pd2(dba) 3 (2.5 mol %) and SPhos (5 mol %) in DMF allows trapping of the corresponding organozinc rea
