Check Digit Verification of cas no
The CAS Registry Mumber 136739-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,3 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136739-32:
(8*1)+(7*3)+(6*6)+(5*7)+(4*3)+(3*9)+(2*3)+(1*2)=147
147 % 10 = 7
So 136739-32-7 is a valid CAS Registry Number.

The co-crystallization of Ru((R)-binap)(η3-Me-allyl)2 and binap dioxide, and synthesis of Ru(Ph2P(CH2)4PPh2)(η 3-Me-allyl)2

The molecular structure of the 2-methylallyl species Ru((R)-binap)(η3-Me-allyl)2 (3) was established by X-ray crystallography of a crystal of 3a, the asymmetric unit of which is composed of half of a molecule of 3 and half of a (R)-(+)-2,2′-bis(diphenylphosphinoyl)-1,1′-binaphthyl(binap dioxide) molecule, co-crystallized with two disordered deuterobenzenes; crystals of 3a are tetragonal, space group I422, with Z=8, a=21.344(1) A and c=36.453(2) A. The structure was solved by direct methods and refined by full-matrix least-squares procedures to R=0.034 and Rw=0.032 for 3431 reflections with I≥3σ(I). The 1,4-bis(diphenylphosphino)butane (dppb) analogue (2) of 3 was also prepared and characterized by 1H and 31P{1H}-NMR spectroscopy and elemental analysis, and the reactivities of 2 and 3 toward halogen acids are discussed.
