123745-44-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123745-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,4 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123745-44:
(8*1)+(7*2)+(6*3)+(5*7)+(4*4)+(3*5)+(2*4)+(1*4)=118
118 % 10 = 8
So 123745-44-8 is a valid CAS Registry Number.

The effect of ultrasound and of phosphine and phosphine-oxides on the Khand reaction
Billington, David C.,Helps, I. Malcolm,Pauson, Peter L.,Thomson, William,Willison, Debra
, p. 233 - 242 (2007/10/02)
Ultrasonic irradation allows the Khand reaction to be conducted rapidly at low temperatures.Addition of phosphine oxides to the reaction mixture significantly increases yields in most cases.
