Check Digit Verification of cas no

The CAS Registry Mumber 62731-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,7,3 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62731-43:
(7*6)+(6*2)+(5*7)+(4*3)+(3*1)+(2*4)+(1*3)=115
115 % 10 = 5
So 62731-43-5 is a valid CAS Registry Number.

Synthesis and characterization of a doubly base-stabilized B 3H6+ analogue

Schulenberg, Nikola,Wadepohl, Hubert,Himmel, Hans-Joerg

, p. 10444 - 10447 (2011)

The answer to an old question: A doubly base-stabilized B3H 6+ analogue (see structure: B green, C gray, N blue, H light gray, H on C not shown) has been synthesized and completely characterized. Quantum-chemical calculations on a simplified model confirmed the presence of closed B-B-B three-center bonding and σ-aromatic character. Copyright

Regio- and Stereoselective Cross-aldol Reactions via Dialkylboryl Triflates

Inoue, Tan,Mukaiyama, Teruaki

, p. 174 - 178 (2007/10/02)

New borylating reagents, (Bu2BOTf and 9-BBNOTf), were prepared in high yields.The triflates reacted with enolizable ketones in the presence of tertiary amines to generate selectively one of the regioisomers of vinyloxyboranes by the choice of the reagents (the dialkylboryl triflates and tertiary amines) under mild reaction conditions.Vinyloxyboranes thus generated showed remarkable reactivity toward aldehydes to give only one regioisomer of the corresponding cross-aldols in good yields.High stereoselectivity was also observed in these reactions.
