97188-21-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97188-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,8 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97188-21:
(7*9)+(6*7)+(5*1)+(4*8)+(3*8)+(2*2)+(1*1)=171
171 % 10 = 1
So 97188-21-1 is a valid CAS Registry Number.

Pyrrole chemistry. XXVIII. Substitution reactions of 1-(phenylsulfonyl)pyrrole and some derivatives

Anderson, Hugh J.,Loader, Charles E.,Xu, Ru Xun,Le, Nghia,Gogan, Niall J.,et al.

, p. 896 - 902 (2007/10/02)

The preparative value of the 1-(phenylsulfonyl) N-blocking and directing group for the synthesis of 3-acylpyrroles has been further evaluated.Acetylation and benzoylation are strongly regiospecific and give good yields.However, the regiospecificity is not general and other substitution reactions give mixtures of 2- and 3-substitution or even mostly 2-substitution.Friedel and Crafts tert-butylation gives 3-tert-butyl-1-(phenylsulfonyl)pyrrole and provides a useful route to tert-butylpyrrole, but ethylation and isopropylation give mixtures.Acylations of 2- and 3-alkyl-1-(phenylsulfonyl)pyrroles show little evidence of useful regiospecificity.

PYRROLE CHEMISTRY XXV: A SIMPLIFIED SYNTHESIS OF SOME 3-SUBSTITUTED PYRROLES

Xu, Ru Xun,Anderson, Hugh J.,Gogan, Niall J.,Loader, Charles E.,McDonald, Robert

, p. 4899 - 4900 (2007/10/02)

A new synthesis is reported which allows the rapid preparation in good yield of 3-aroyl-, 3-acetyl- and 3-nitro- pyrroles from pyrrole utilizing the 1-benzenesulfonyl group as a blocking group.
