Check Digit Verification of cas no

The CAS Registry Mumber 1432044-45-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,2,0,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1432044-45:
(9*1)+(8*4)+(7*3)+(6*2)+(5*0)+(4*4)+(3*4)+(2*4)+(1*5)=115
115 % 10 = 5
So 1432044-45-5 is a valid CAS Registry Number.

Amino Acid Ligands for Ruthenium(II)-Catalyzed C–H Arylation of Aryltetrazoles with Chlorides: Expedient Access to Antihypertension Drugs

Hubrich, Jonathan,Ackermann, Lutz

, p. 3700 - 3704 (2016)

Versatile ruthenium(II) complexes derived from amino acids enabled the first general C–H arylations of aryltetrazoles with inexpensive aryl chlorides. The user-friendly Piv-Val-OH-based ruthenium(II) catalyst was characterized by a broad substrate scope, excellent functional group tolerance, and high catalytic activity. Thereby, the ruthenium(II) catalysis set the stage for the step-economical preparation of the blockbuster antihypertension drug Valsartan, while displaying unique robustness in the C–H arylation regime.

Carboxylate-assisted ruthenium(II)-catalyzed C-H arylations of 5-aryl tetrazoles: Step-economical access to Valsartan

Diers, Emelyne,Phani Kumar,Mejuch, Tom,Marek, Ilan,Ackermann, Lutz

, p. 4445 - 4453 (2013/06/27)

Carboxylate assistance was key to success for highly efficient ruthenium-catalyzed direct ortho-arylations of tetrazolyl-substituted arenes with aryl halides and triflates in the absence of phosphine ligands. Thus, ruthenium(II) biscarboxylates allowed for C-H bond functionalizations with excellent chemo- and site-selectivities, which set the stage for an atom- and step-economical access to key angiotensin-II-receptor blockers. Mechanistic studies revealed the C-H bond metalation to be reversible, and were suggestive of a rate-determining reductive elimination.
