Check Digit Verification of cas no

The CAS Registry Mumber 129158-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,5 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129158-81:
(8*1)+(7*2)+(6*9)+(5*1)+(4*5)+(3*8)+(2*8)+(1*1)=142
142 % 10 = 2
So 129158-81-2 is a valid CAS Registry Number.

Copper-Catalyzed γ-Selective and Stereospecific Allylic Cross-Coupling with Secondary Alkylboranes

Yasuda, Yuto,Nagao, Kazunori,Shido, Yoshinori,Mori, Seiji,Ohmiya, Hirohisa,Sawamura, Masaya

supporting information, p. 9666 - 9670 (2015/06/30)

The scope of the copper-catalyzed coupling reactions between organoboron compounds and allylic phosphates is expanded significantly by employing triphenylphosphine as a ligand for copper, allowing the use of secondary alkylboron compounds. The reaction proceeds with complete γ-E-selectivity and preferential 1,3-syn stereoselectivity. The reaction of γ-silicon-substituted allylic phosphates affords enantioenriched α-stereogenic allylsilanes.

Reversible 1,3-anti/syn-stereochemical courses in copper-catalyzed γ-selective allyl-alkyl coupling between chiral allylic phosphates and alkylboranes

Nagao, Kazunori,Yokobori, Umi,Makida, Yusuke,Ohmiya, Hirohisa,Sawamura, Masaya

supporting information; scheme or table, p. 8982 - 8987 (2012/07/02)

The stereochemical courses of the copper-catalyzed allyl-alkyl coupling between enantioenriched chiral allylic phosphates and alkylboranes were switchable between 1,3-anti and 1,3-syn selectivities by the choice of solvents and achiral alkoxide bases with different steric demands. The reactions with γ-silylated allylic phosphates allow efficient synthesis of enantioenriched chiral allylsilanes with tertiary or quaternary carbon stereogenic centers. Cyclic and acyclic bimodal participation of alkoxyborane species in an organocopper addition-elimination sequence is proposed to account for the phenomenon of the anti/syn-stereochemical reversal.
