1312919-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312919-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,9,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1312919-33:
(9*1)+(8*3)+(7*1)+(6*2)+(5*9)+(4*1)+(3*9)+(2*3)+(1*3)=137
137 % 10 = 7
So 1312919-33-7 is a valid CAS Registry Number.

V-shaped nematogens with the "magic bent angle"
Seltmann, Jens,Mueller, Kathrin,Klein, Susanne,Lehmann, Matthias
, p. 6680 - 6682 (2011/07/31)
V-shaped nematogens 1a-c and 2a-b with benzodithiophene bending units have been synthesised. The derivatives 1a-c comprise a flat core with a bending angle of 109°, which is almost the tetrahedral angle proposed to be optimal in the realization of mesogen
