Check Digit Verification of cas no
The CAS Registry Mumber 1256360-24-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,3,6 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1256360-24:
(9*1)+(8*2)+(7*5)+(6*6)+(5*3)+(4*6)+(3*0)+(2*2)+(1*4)=143
143 % 10 = 3
So 1256360-24-3 is a valid CAS Registry Number.

Lewis Acid–Base Interaction-Controlled ortho-Selective C?H Borylation of Aryl Sulfides

An iridium/bipyridine-catalyzed ortho-selective C?H borylation of aryl sulfides was developed. High ortho-selectivity was achieved by a Lewis acid–base interaction between a boryl group of the ligand and a sulfur atom of the substrate. This is the first example of a catalytic and regioselective C?H transformation controlled by a Lewis acid–base interaction between a ligand and a substrate. The C?H borylation reaction could be conducted on a gram scale, and with a bioactive molecule as a substrate, demonstrating its applicability to late-stage regioselective C?H borylation. A bioactive molecule was synthesized from an ortho-borylated product by converting the boryl and methylthio groups of the product.
