Check Digit Verification of cas no

The CAS Registry Mumber 93915-81-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,1 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93915-81:
(7*9)+(6*3)+(5*9)+(4*1)+(3*5)+(2*8)+(1*1)=162
162 % 10 = 2
So 93915-81-2 is a valid CAS Registry Number.

Stereoselective [4+2]-Cycloaddition with Chiral Alkenylboranes

Brown, M. Kevin,Houk, K. N.,Ni, Dongshun,Witherspoon, Brittany P.,Zhang, Hong,Zhou, Chen

supporting information, p. 11432 - 11439 (2020/05/18)

A method for the stereoselective [4+2]-cycloaddition of alkenylboranes and dienes is presented. This transformation was accomplished through the introduction of a new strategy that involves the use of chiral N-protonated alkenyl oxazaborolidines as dieneophiles. The reaction leads to the formation of products that can be readily derivatized to more complex structural motifs through stereospecific transformations of the C?B bond such as oxidation and homologation. Detailed computation evaluation of the reaction has uncovered a surprising role of the counterion on stereoselectivity.

Trichodiene Synthase. Synergistic Inhibition by Inorganic Pyrophosphate and Aza Analogs of the Bisabolyl Cation

Cane, David E.,Yang, Guohan,Coates, Robert M.,Pyun, Hyung-Jung,Hohn, Thomas M.

, p. 3454 - 3462 (2007/10/02)

A series of aza analogs of the bisabolyl and α-terpinyl cations were tested as inhibitors of the sesquiterpene cyclase, trichodiene synthase.Both (R)- and (S)-16 and (R)- and (S)-13 as well as trimethylamine were only weak inhibitors when incubated alone.In the presence of inorganic pyrophosphate, itself a known competitive inhibitor of trichodiene synthase, all five amines showed strong cooperative competitive inhibition with an enhancement factor estimated to be 10-40.The apparent induced inhibition constant αKJ decreased in going from trimethylamine to the monoterpene analogs 13 and was strongest for the sesquiterpene analogs 16, indicating that both electrostatic and hydrophobic interactions are important in the binding of each intermediate analog.The cyclase showed little discrimination, however, between the individual enantiomers of each inhibitor.
