Check Digit Verification of cas no

The CAS Registry Mumber 10271-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,7 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 10271-57:
(7*1)+(6*0)+(5*2)+(4*7)+(3*1)+(2*5)+(1*7)=65
65 % 10 = 5
So 10271-57-5 is a valid CAS Registry Number.

Pd nanoparticles immobilized on poly(NIPAM-co-4-VP) hydrogel: Highly active and reusable catalyst for carbon-carbon coupling reactions in water

Lee, Yongwoo,Hong, Myeng Chan,Ahn, Hyunseok,Yu, Jeongmok,Rhee, Hakjune

, p. 80 - 93 (2014)

Poly(N-isopropylacrylamide-co-4-vinylpyridine) [poly(NIPAM-co-4-VP)] co-polymer exhibited inverse temperature solubility with a lower critical solution temperature (LCST) in water. Pd nanoparticles were immobilized on these poly(NIPAM-co-4-VP) hydrogels. The heterogeneous Pd catalyst showed high catalytic activities for carbon-carbon coupling reactions, such as Suzuki-Miyaura, Heck-Mizoroki, and Sonogashira coupling reactions in water. The Pd catalyst immobilized on poly(NIPAM-co-4-VP) hydrogel (NIPAM:4-VP = 1:1 M ratio) showed an excellent recyclability and excellent yield for carbon-carbon coupling reactions.

Abstract The catalytic activity of [Pd{C6H4(CH2N(CH2Ph)2)} (μ-Br)]2 complex as an efficient, stable and non-sensitive to air and moisture catalyst was investigated in the Sonogashira cross-coupling reaction under microwave irradiation. In the presence of catalytic amount of this homogeneous catalytic system, various aryl halides were efficiently coupled with phenylacetylene under copper-free conditions. The substituted internal alkynes were produced in excellent yields in short reaction times in NMP at 100°. The combination of dimeric complex as homogenous catalyst and microwave irradiation and also NMP as microwave-active polar solvent gave higher yields in shorter reaction times.
