Check Digit Verification of cas no

The CAS Registry Mumber 1357495-82-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,4,9 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1357495-82:
(9*1)+(8*3)+(7*5)+(6*7)+(5*4)+(4*9)+(3*5)+(2*8)+(1*2)=199
199 % 10 = 9
So 1357495-82-9 is a valid CAS Registry Number.

Synthesis of 3,4-fused cycloalkanopyrroles by 1,3-dipolar cycloaddition

Kelly, James M.,Leeper, Finian J.

, p. 819 - 821 (2012/03/10)

The synthesis of a number of 3,4-fused cycloalkanopyrroles bearing substituents on the cycloalkane ring was accomplished by 1,3-dipolar cycloaddition. The yield of the cyclization appeared to depend on the base-sensitivity of the Michael acceptor, but the method is applicable across a broad range of cyclic α,β-unsaturated ketone esters. Functional group transformations can be undertaken following pyrrole synthesis to increase the diversity of cycloalkanopyrroles accessible by this method. One pyrrole thus made is a diester of a conformationally-constrained analogue of porphobilinogen, the precursor of the natural tetrapyrroles.
