Check Digit Verification of cas no

The CAS Registry Mumber 88043-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,0,4 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88043-21:
(7*8)+(6*8)+(5*0)+(4*4)+(3*3)+(2*2)+(1*1)=134
134 % 10 = 4
So 88043-21-4 is a valid CAS Registry Number.

Selective CDK6 degradation mediated by cereblon, VHL, and novel IAP-recruiting PROTACs

Ahmed, Adil,Anderson, Niall A.,Benowitz, Andrew B.,Cryan, Jenni,Dai, Han,McGonagle, Grant A.,Rozier, Christine

Inhibitors of CDK4 and CDK6 have emerged as important FDA-approved treatment options for breast cancer patients. The properties and pharmacology of CDK4/6 inhibitor medicines have been extensively profiled, and investigations into the degradation of these

Reusable shuttles for exchangeable functional cargos: Reversibly assembled, magnetically powered organocatalysts for asymmetric aldol reactions

Mendoza, Carolina,de la Croix, Augustin,Riente, Paola,Llorens, Lluís,de Mendoza, Javier,Pericàs, Miquel A.

supporting information, (2019/09/17)

A supramolecular approach has been followed to support adamantyl substituted proline organocatalysts onto the surface of magnetite nanoparticles decorated with a β-cyclodextrin motif. The resulting magnetic nanoparticles (ca. ~10 nm diameter) were used as modular, magnetically recyclable catalysts in the asymmetric aldol reaction of aromatic aldehydes with cyclic ketones in water. The catalytic assemblies can be easily dismantled in organic media, and the recovered nanoparticles (magnetically powered chemical shuttles) re-complexed with another suitably substituted catalytic unit (replaceable functional cargo).

, p. 13327 - 13334 (2018/10/20)

Polyproline sequences are highly abundant in prokaryotic and eukaryotic proteins, where they serve as key components of secondary structure. To date, construction of the proline-proline motif has not been possible owing to steric congestion at the ligatio
