Check Digit Verification of cas no
The CAS Registry Mumber 697252-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,7,2,5 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 697252-26:
(8*6)+(7*9)+(6*7)+(5*2)+(4*5)+(3*2)+(2*2)+(1*6)=199
199 % 10 = 9
So 697252-26-9 is a valid CAS Registry Number.

The Catalytic Asymmetric Intermolecular Prins Reaction
Diáz-Oviedo, C. David,Maji, Rajat,List, Benjamin
supporting information, p. 20598 - 20604 (2021/12/14)
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.
