Check Digit Verification of cas no

The CAS Registry Mumber 1239762-33-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,7,6 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1239762-33:
(9*1)+(8*2)+(7*3)+(6*9)+(5*7)+(4*6)+(3*2)+(2*3)+(1*3)=174
174 % 10 = 4
So 1239762-33-4 is a valid CAS Registry Number.

The self-assembly of six-petal microflowers by hydrogen-bonded shape-persistent triangular aromatic hydrazide derivatives

Lin, Jian-Bin,Wang, Gui-Tao,Jiang, Xi-Kui,Li, Zhan-Ting

scheme or table, p. 4221 - 4224 (2010/09/12)

Six-petal microflowers have been self-assembled in methanol from C 3-symmetric shape-persistent triangular aromatic hydrazide derivatives. Nine intramolecular hydrogen bonds are used to enhance the planarity of the aromatic backbone, while six 2-(2-(2-methoxyethoxy)ethoxy)- ethoxyl groups are appended to the rigid aromatic backbone. Scanning electron microscopy (SEM) images show that the molecules form unique six-petal flower-like aggregates in methanol. A self-assembling mechanism that is similar to the formation of snowflakes has been proposed.
