1569905-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1569905-32-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,9,0 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1569905-32:
(9*1)+(8*5)+(7*6)+(6*9)+(5*9)+(4*0)+(3*5)+(2*3)+(1*2)=213
213 % 10 = 3
So 1569905-32-3 is a valid CAS Registry Number.

Mechanism of phosphinidene complex arylation by arylboronic acids
Ng, Yong Xiang,Mathey, Francois
, p. 1322 - 1324 (2014)
The arylation reaction of terminal phosphinidene complexes [RP-W(CO) 5] by arylboronic acids is very sensitive to steric hindrance and the electronic properties of the substituents on the aryl ring. On the basis of DFT calculations and addition
