Check Digit Verification of cas no
The CAS Registry Mumber 174148-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,1,4 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 174148-87:
(8*1)+(7*7)+(6*4)+(5*1)+(4*4)+(3*8)+(2*8)+(1*7)=149
149 % 10 = 9
So 174148-87-9 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.
