Check Digit Verification of cas no

The CAS Registry Mumber 1543345-12-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,3,3,4 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1543345-12:
(9*1)+(8*5)+(7*4)+(6*3)+(5*3)+(4*4)+(3*5)+(2*1)+(1*2)=145
145 % 10 = 5
So 1543345-12-5 is a valid CAS Registry Number.

Relay catalysis using a gold(i) complex/Bronsted acid binary system for the synthesis of bezoxasiloles

Horino, Yoshikazu,Takahashi, Yu,Nakashima, Yuichi,Abe, Hitoshi

, p. 6215 - 6218 (2014)

A strategy for the synthesis of synthetically useful benzoxasilole derivatives by combining a gold(i) complex/Bronsted acid binary system and a temporary silicon tether method has been developed that involves relay catalytic cascade intramolecular allylation of alkynes by a gold(i) complex and addition of silanols to enones by a Bronsted acid.
