The CAS Registry Mumber 107826-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,8,2 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 107826-07:
(8*1)+(7*0)+(6*7)+(5*8)+(4*2)+(3*6)+(2*0)+(1*7)=123
123 % 10 = 3
So 107826-07-3 is a valid CAS Registry Number.

A FACILE ACCESS TO MASKED ISOBENZOFURANS ; HIGH EXO-STEREOSELECTIVITY IN THE DIELS-ALDER REACTIONS OF 4,7-DIHYDRO-4,7-ETHANOISOBENZOFURAN.

Stephan, Dominique,Gorgues, Alain,Coq, Andre Le

, p. 4295 - 4298 (2007/10/02)

The isobenzofuran derivatives precursors 4a-c are readily prepared from 1 ; their Diels-Alder adducts with cis-dienophiles present a stereochemistry endo>exo from 4b,c and, interestingly, only exo (towards the furan moiety) from 4a.
