Check Digit Verification of cas no
The CAS Registry Mumber 20515-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,1 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20515-15:
(7*2)+(6*0)+(5*5)+(4*1)+(3*5)+(2*1)+(1*5)=65
65 % 10 = 5
So 20515-15-5 is a valid CAS Registry Number.

Exploring the reaction of iodine with α-diazo esters
Werardo, Giancarlo,Geatti, Paola,Gambi, Alberto
experimental part, p. 24 - 30 (2009/07/26)
In this paper we describe the unprecedented reaction between a-diazo esters 1 and iodine. The reaction, carried out in the presence of aqueous NaHCO 3, afforded the Z-isomer of the corresponding unsaturated-2-iodo ester 8, The configuration of
