Check Digit Verification of cas no

The CAS Registry Mumber 103765-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,6 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103765-33:
(8*1)+(7*0)+(6*3)+(5*7)+(4*6)+(3*5)+(2*3)+(1*3)=109
109 % 10 = 9
So 103765-33-9 is a valid CAS Registry Number.

Synthesis and relative diatropicity of a remarkably aromatic thia[13]annulene

Mitchell, Reginald H.,Iyer, Vivekanantan S.

, p. 722 - 725 (2007/10/03)

2,4-Bis(bromomethyl)-3-methylthiophene was synthesised as an intermediate to prepare the strained thiophenobenzophanediene 11, which readily thermally valence isomerizes to the novel thia[13]annulene 10. This thia-annulene is notably diatropic and shows about 40% of the ring current of the parent bridged [14]annulene 9, which is substantially more than an analogous oxaannulene, 18, and substantially less than the azaannulene 19.
