Check Digit Verification of cas no

The CAS Registry Mumber 1233934-04-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,9,3 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1233934-04:
(9*1)+(8*2)+(7*3)+(6*3)+(5*9)+(4*3)+(3*4)+(2*0)+(1*4)=137
137 % 10 = 7
So 1233934-04-7 is a valid CAS Registry Number.

The construction of H-shaped fluorescent materials based on building blocks consisting of triphenylamine and fluorene

Zhang, Cheng,Zhang, Yu-Jian,Xiang, Wen-Qin,Hu, Bin,Ouyang, Mi,Xu, Yi,Ma, Chun-An

supporting information; experimental part, p. 520 - 521 (2010/09/05)

A class of complicated 9,9-diarylfluorenes as nonplanar building blocks were synthesized and utilized to prepare a novel H-shaped oligofluorene. High glass transition temperatures and excellent solubility of the obtained oligomers indicated the 9,9diarylfluorenes would be promising building blocks for the construction of H-shaped optoelectronic materials.
