Check Digit Verification of cas no

The CAS Registry Mumber 1354723-64-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,4,7,2 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1354723-64:
(9*1)+(8*3)+(7*5)+(6*4)+(5*7)+(4*2)+(3*3)+(2*6)+(1*4)=160
160 % 10 = 0
So 1354723-64-0 is a valid CAS Registry Number.

Synthesis of conjugated allenes through copper-catalyzed γ-selective and stereospecific coupling between propargylic phosphates and aryl- or alkenylboronates

Yang, Mingyu,Yokokawa, Natsumi,Ohmiya, Hirohisa,Sawamura, Masaya

, p. 816 - 819 (2012/04/05)

A Cu-catalyzed γ-selective coupling reaction between propargylic phosphates and aryl- or alkenylboronates afforded aryl- or alkenyl-conjugated allenes. The reaction showed excellent functional group compatibility in both the propargylic substrates and the boronates. The reaction of an enantioenriched propargylic phosphate proceeded with excellent chirality transfer with 1,3-anti stereochemistry to give axially chiral aryl- and alkenylallenes.
