Check Digit Verification of cas no

The CAS Registry Mumber 220239-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,3 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220239-29:
(8*2)+(7*2)+(6*0)+(5*2)+(4*3)+(3*9)+(2*2)+(1*9)=92
92 % 10 = 2
So 220239-29-2 is a valid CAS Registry Number.

Chemoselective reduction of a lactam carbonyl group in the presence of a gem-dicarboxylate by sodium borohydride and iodine: A facile entry to N-aryl trisubstituted pyrroles

Haldar, Pranab,Ray, Jayanta K.

, p. 8229 - 8231 (2003)

Several N-aryl γ-lactam gem dicarboxylates were chemoselectively reduced to cyclic amine diesters by using sodium borohydride-iodine system. The reduction in all cases was completed within 2.5 h after refluxing in THF. The cyclic amine products were isolated after aqueous (acidic) workup in good yields. Hydrolytic decarboxylation followed by dehydrogenation produced N-aryl carboethoxy pyrroles.

Synthesis of some thieno gamma lactam monocarboxylic acids with high antibacterial activity: A new look at an old molecular system

Kar, Gandhi K.,Roy, Bidhan C.,Adhikari, Sujit Das,Ray, Jayanta K.,Brahma, Nitosh K.

, p. 2397 - 2403 (1998)

Synthesis and antibacterial activity of some novel monocyclic thienyl gamma lactams are reported. The compounds have been synthesized by a two-step process consisting of, first, intermolecular Michael addition, followed by intramolecular amidification bet
