Check Digit Verification of cas no

The CAS Registry Mumber 33421-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,2 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33421-18:
(7*3)+(6*3)+(5*4)+(4*2)+(3*1)+(2*1)+(1*8)=80
80 % 10 = 0
So 33421-18-0 is a valid CAS Registry Number.

A chiral picolinic acid ligand, Cl-NAPH-PyCOOH, for CPRU-catalyzed dehydrative allylation: Design, synthesis, and properties

Tanaka, Shinji,Suzuki, Yusuke,Kimura, Takahiro,Kitamura, Masato

, p. 1707 - 1720 (2019/10/01)

A CpRu/Br?nsted acid-combined catalyst, CpRu(II)/pico-linic acid (PyCOOH), acts as an efficient catalyst for the allyl protection/deprotection of alcohols. This discovery has resulted in the development of a new axially chiral ligand, Cl-Naph-PyCOOH (2a;
