1257334-10-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1257334-10-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,3 and 4 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257334-10:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*3)+(3*4)+(2*1)+(1*0)=143
143 % 10 = 3
So 1257334-10-3 is a valid CAS Registry Number.

Iridium-catalyzed arene ortho -silylation by formal hydroxyl-directed C-H activation
Simmons, Eric M.,Hartwig, John F.
, p. 17092 - 17095 (2011/03/01)
A strategy for the ortho-silylation of aryl ketone, benzaldehyde, and benzyl alcohol derivatives has been developed in which a hydroxyl group formally serves as the directing element for Ir-catalyzed arene C-H bond activation. One-pot generation of a (hyd
