Check Digit Verification of cas no

The CAS Registry Mumber 86429-24-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,4,2 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 86429-24:
(7*8)+(6*6)+(5*4)+(4*2)+(3*9)+(2*2)+(1*4)=155
155 % 10 = 5
So 86429-24-5 is a valid CAS Registry Number.

Boration Reactions with 1-Alkynes

Binnewirtz, Ralf-Juergen,Klingenberger, Helmut,Welte, Rainer,Paetzold, Peter

, p. 1271 - 1284 (2007/10/02)

Halodiorganoboranes R2BHal(R = Et, Ph) as well as benzyldihaloboranes PhCH2BHal2 undergo a regiospecific addition to the triple-bond of 1-alkynes ACCR'.The reversible haloboration (1) gives Z-alkenes as the more stable isomers.At elevated temperatures, the irreversible 1,1-organoboration (2) predominates, accompanied by a 1,2-transfer of A, whereas the 1,2-organoboration (3) is observed only as an unimportant side-reaction in a few cases.The cyclisation (4) occurs as a sequence of cis-haloboration and intramolecular aromatic alkenylation in the case of PhCH2BCl2 as borating agent.
