Check Digit Verification of cas no

The CAS Registry Mumber 188053-41-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,0,5 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188053-41:
(8*1)+(7*8)+(6*8)+(5*0)+(4*5)+(3*3)+(2*4)+(1*1)=150
150 % 10 = 0
So 188053-41-0 is a valid CAS Registry Number.

Synthesis and conformational behaviour of 2-phenylperhydropyrrolo[1,2-4][1,3,4]oxadiazine and 2-phenylperhydropyrido[1,2-d][1,3,4]oxadiazine; new heterocyclic ring systems

Rosling, Ari,Fueloep, Ferenc,Sillanpaeae, Reijo,Mattinen, Jorma

, p. 95 - 106 (2007/10/03)

Hydrazino alcohols, 1-amino-2-hydroxymethylpyrrolidine (1) and 1-amino-2-hydroxymethylpiperidine (2), were synthesized and subsequently ring closured with ethyl benzimidate to the title compounds (7) and (8), which have new ring systems. Variabletemperature 1H nmr measurements, supported by X-ray analysis, indicated that pyrrolo[1,2-d][1,3,4]oxadiazine (7) exists exclusively in a cis-fused conformation (in CDCl3 at room temperature), whereas pyrido[1,2-d][1,3,4]oxadiazine (8) adopts a trans-fused conformation.
