Check Digit Verification of cas no

The CAS Registry Mumber 53348-88-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,3,4 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 53348-88:
(7*5)+(6*3)+(5*3)+(4*4)+(3*8)+(2*8)+(1*8)=132
132 % 10 = 2
So 53348-88-2 is a valid CAS Registry Number.

Tandem Sonogashira-Hagihara coupling/cycloisomerization reactions of ethynylboronic acid MIDA ester to afford 2-heterocyclic boronic acid MIDA esters: A concise route to benzofurans, indoles, furopyridines and pyrrolopyridines

Sakurai, Yohji

, p. 1322 - 1336 (2017)

A one-pot process that provides direct access to 2-heterocyclic MIDA (N-methyliminodiacetic acid) boronates has been developed. The reaction of 2-iodophenols or 2-iodoanilines with ethynylboronic acid MIDA ester readily afforded 2-substituted heterocyclic compounds. Amidine and phosphazene bases, especially TMG (1,1,3,3-tetramethylguanidine) assumed an important role in the tandem Sonogashira-Hagihara coupling/cycloisomerization reactions.
