Check Digit Verification of cas no

The CAS Registry Mumber 1594135-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,4,1,3 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1594135-20:
(9*1)+(8*5)+(7*9)+(6*4)+(5*1)+(4*3)+(3*5)+(2*2)+(1*0)=172
172 % 10 = 2
So 1594135-20-2 is a valid CAS Registry Number.

Catalytic Enantioselective Synthesis and Switchable Chiroptical Property of Inherently Chiral Macrocycles

Tong, Shuo,Li, Jiang-Tao,Liang, Dong-Dong,Zhang, Yan-E,Feng, Qi-Yun,Zhang, Xin,Zhu, Jieping,Wang, Mei-Xiang

, p. 14432 - 14436 (2020)

We report herein a strategy to construct enantiopure inherently chiral macrocycles, ABCD-type heteracalix[4]aromatics, through a catalytic enantioselective intramolecular C-N bond forming reaction. A chiral ligand-palladium complex was found to efficiently induce the inherent chirality of molecules during the macrocyclization process with ee values up to >99%. The resulting ABCD-type heteracalix[4]aromatics displayed excellent and pH-triggered switchable electronic circular dichroism and circularly polarized luminescence properties.
