5685-21-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5685-21-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5685-21:
(6*5)+(5*6)+(4*8)+(3*5)+(2*2)+(1*1)=112
112 % 10 = 2
So 5685-21-2 is a valid CAS Registry Number.

Carbon-carbon bond forming reactions of ω-oxylactams in acid and neutral medium

Speckamp, W. N.,Boer, J. J. J. de

, p. 405 - 409 (2007/10/02)

1,3-Dicarbonyl compounds and hydroxybenzenes condense under the influence of acid with ω-hydroxylactams 1-7 in an intermolecular process, thereby affording ω-alkylated lactams 8-13.The reactive intermediate in the carbon-carbon bond forming step is a cyclic N-acyliminium ion.The intramolecular variant affords keto ester 19.Upon activation of the ω-hydroxylactam as a hexafluoroisopropoxy ester, condensations with cyanide in aprotic polar solvents under neutral conditions become possible.
