Check Digit Verification of cas no

The CAS Registry Mumber 1261990-57-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,9,9 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1261990-57:
(9*1)+(8*2)+(7*6)+(6*1)+(5*9)+(4*9)+(3*0)+(2*5)+(1*7)=171
171 % 10 = 1
So 1261990-57-1 is a valid CAS Registry Number.

Transition-metal free synthesis of diaryl vinyl selenides: A simple synthetic approach with high selectivity

Mohan, Balaji,Hwang, Sori,Woo, Hyunje,Park, Kang Hyun

, p. 2699 - 2702 (2014/04/17)

A simple, highly efficient synthetic protocol is developed for the synthesis of unsymmetrical diaryl vinyl selenides from diaryldiselenide and β-bromo styrene under transition-metal free conditions in N,N′-dimethyl propylene urea and 130 °C to afford high yields and excellent selectivities. This method provides a new strategy to fabricate a wide variety of important substituted molecular skeletons and an alternative to conventionally used metal salts, additives, and ligands.

Glycerol as a promoting medium for cross-coupling reactions of diaryl diselenides with vinyl bromides

Gonalves, Loren C.,Fiss, Gabriela F.,Perin, Gelson,Alves, Diego,Jacob, Raquel G.,Lenard?o, Eder J.

supporting information; experimental part, p. 6772 - 6775 (2011/02/24)

We described herein the use of glycerol as a novel solvent in the cross-coupling reaction of diaryl diselenides with vinyl bromides catalyzed by CuI. This cross-coupling reaction was performed with diaryl diselenides and (Z)- or (E)-vinyl bromides bearing electron-withdrawing and electron-donating groups, affording the corresponding vinyl selenides in good to excellent yields. The mixture glycerol/catalyst can be directly reused for further cross-coupling reactions.
