Check Digit Verification of cas no
The CAS Registry Mumber 17475-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,7 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17475-41:
(7*1)+(6*7)+(5*4)+(4*7)+(3*5)+(2*4)+(1*1)=121
121 % 10 = 1
So 17475-41-1 is a valid CAS Registry Number.

Solid-phase synthesis of isoindolinones and naturally-occurring benzobutyrolactones (phthalides) using a cyclative-cleavage approach
Knepper, Kerstin,Ziegert, Robert E.,Br?se, Stefan
, p. 8591 - 8603 (2007/10/03)
Starting from Merrifield resin, 2-formylbenzoic acids were immobilized on solid supports. Reactions between immobilized 2-formylbenzoic acids and different organometallic reagents (Grignard reagents, zinc reagents, allyl silanes via Sakurai type reactions) furnished secondary alcohols which cyclized depending on the metal counter ion and reaction conditions, forming benzoannelated lactones. Asymmetric synthesis was possible on the resin using chiral [2.2]paracyclophane ligands. While the reaction of immobilized ortho-carboxy benzaldehydes with primary amines at elevated temperatures yielded 3-hydroxyisoindolinones, a reaction at ambient temperature allowed imine formation, which underwent 1,2-addition-cleavage reaction with various nucleophiles, yielding isoindolinones with three points of diversity.
