Check Digit Verification of cas no
The CAS Registry Mumber 5471-63-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,7 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5471-63:
(6*5)+(5*4)+(4*7)+(3*1)+(2*6)+(1*3)=96
96 % 10 = 6
So 5471-63-6 is a valid CAS Registry Number.

A simple, practical, and efficient method for one-pot synthesis of symmetric and unsymmetrical 1,3-diarylisobenzofurans has been developed by sequential reactions of methyl 2-formylbenzoate with two identical or different aryl metal species.
Facile Sc(OTf)3-catalyzed generation and successive aromatization of isobenzofuran from o -dicarbonylbenzenes
Nishina, Yuta,Kida, Tatsuya,Ureshino, Tomonari
supporting information; experimental part, p. 3960 - 3963 (2011/10/01)
Isobenzofuran can be prepared from o-phthalaldehyde using hydrosilane. The formed isobenzofuran is trapped by an alkene via a Diels-Alder reaction. Further dehydration proceeds to furnish the conjugated aromatic compound. This multistep reaction was promoted by catalytic amounts of Sc(OTf)3.
