Check Digit Verification of cas no

The CAS Registry Mumber 164584-95-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,5,8 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 164584-95:
(8*1)+(7*6)+(6*4)+(5*5)+(4*8)+(3*4)+(2*9)+(1*5)=166
166 % 10 = 6
So 164584-95-6 is a valid CAS Registry Number.

Preparation of 3-Benzoylpenems and Penem Amides by Wittig Methodology

Pearson, Neil D.,Smale, Terence C.,Southgate, Robert

, p. 4493 - 4496 (1995)

Condensation of phenyl glyoxal with azetidin-2-ones (1a-c) gave the hemi-aminals (2a-c).Subsequent conversions produced the 4-(formylthio)phosphoranes (4a-c) which gave on heating the 3-benzoylpenems (5a-c), formed by intramolecular Wittig cyclisation.Thermal isomerisation of trans-6-substituted-3-benzoylpenems allowed the preparation of the cis-6-substituted-3-benzoylpenems (7a-c).Using similar methodology the penem amides (7d-e) were synthesised.
