Check Digit Verification of cas no
The CAS Registry Mumber 186135-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,1,3 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 186135-53:
(8*1)+(7*8)+(6*6)+(5*1)+(4*3)+(3*5)+(2*5)+(1*3)=145
145 % 10 = 5
So 186135-53-5 is a valid CAS Registry Number.

Domino syntheses of five-, six- and seven-membered O-, N- and S-heterocycles from α-, β- and γ-substituted carboxylic esters
Loeffler,Schobert
, p. 2799 - 2802 (2007/10/03)
By a one-pot procedure, tetronic acids, tetronates, coumarins, benzoxepinones and their N- and S-analogues are readily accessible from keteneylidene(triphenyl)phosphorane 2 and carboxylic esters bearing OH, NHR or SH groups in an α-, β- or γ-position by an addition/Wittig olefination/(Claisen rearrangement) sequence. This cascade can be controlled by temperature variation. Extension of this procedure by a further addition step yielding annulated bisheterocycles such as the furoquinolone 28 is possible in some cases.
