Check Digit Verification of cas no

The CAS Registry Mumber 1616345-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,3,4 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1616345-57:
(9*1)+(8*6)+(7*1)+(6*6)+(5*3)+(4*4)+(3*5)+(2*5)+(1*7)=163
163 % 10 = 3
So 1616345-57-3 is a valid CAS Registry Number.

Synthesis of chiral dopants based on carbohydrates

Tsuruta, Toru,Koyama, Tetsuo,Yasutake, Mikio,Hatano, Ken,Matsuoka, Koji

, p. 15 - 22 (2014/06/23)

Chiral dopants based on carbohydrates for nematic liquid crystals were synthesized from d-glucose, and their helical twisting power (HTP) values were evaluated. The chiral dopants induced helices in the host nematic liquid crystals. An acetyl derivative having an ether-type glycosidic linkage between carbohydrate and a mesogenic moiety showed the highest HTP value of 10.4 μm-1, while an acetyl derivative having an anomeric ester-type linkage did not show any HTP. It was surprising that this molecule had no HTP despite the presence of chirality in the molecule. A relationship between HTP and specific rotation was not observed in this study.
