Check Digit Verification of cas no

The CAS Registry Mumber 131569-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131569-81:
(8*1)+(7*3)+(6*1)+(5*5)+(4*6)+(3*9)+(2*8)+(1*1)=128
128 % 10 = 8
So 131569-81-8 is a valid CAS Registry Number.

Borylstannylation of alkynes with inverse regioselectivity: Copper-catalyzed three-component coupling using a masked diboron

Yoshida,Takemoto,Takaki

, p. 6297 - 6300 (2015)

A variety of terminal alkynes are facilely convertible into cis-boryl(stannyl)alkenes with inverse regioselectivity to those of the previous borylstannylation by the copper-catalyzed three-component reaction using a masked diboron. The synthetic utility of the resulting boryl(stannyl)alkenes has been demonstrated by chemoselective coupling reactions. This journal is

A New Preparative Method of Buta-1,3-diene and Hexa-1,5-dien-3-yne by Reduction of Butatriene and Hexapentaene, Respectively, with Zn-ZnCl2-H2O

Kishigami, Satoshi,Tanaka, Koichi,Toda, Fumio

, p. 1877 - 1880 (2007/10/02)

The Zn-ZnCl2-H2O reagent was found to be effective for the reduction of aryl group substituted butatrienes and hexapentaenes to buta-1,3-dienes and hexa-1,5-dien-3-ynes, respectively.
