Check Digit Verification of cas no
The CAS Registry Mumber 76968-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,6 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 76968-28:
(7*7)+(6*6)+(5*9)+(4*6)+(3*8)+(2*2)+(1*8)=190
190 % 10 = 0
So 76968-28-0 is a valid CAS Registry Number.

The Catalytic Asymmetric Intermolecular Prins Reaction
Diáz-Oviedo, C. David,Maji, Rajat,List, Benjamin

Despite their significant potential, catalytic asymmetric reactions of olefins with formaldehyde are rare and metal-free approaches have not been previously disclosed. Here we describe an enantioselective intermolecular Prins reaction of styrenes and paraformaldehyde to form 1,3-dioxanes, using confined imino-imidodiphosphate (iIDP) Br?nsted acid catalysts. Isotope labeling experiments and computations suggest a concerted, highly asynchronous addition of an acid-activated formaldehyde oligomer to the olefin. The enantioenriched 1,3-dioxanes can be transformed into the corresponding optically active 1,3-diols, which are valuable synthetic building blocks.
