21898-45-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21898-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,9 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21898-45:
(7*2)+(6*1)+(5*8)+(4*9)+(3*8)+(2*4)+(1*5)=133
133 % 10 = 3
So 21898-45-3 is a valid CAS Registry Number.

Palladium-catalyzed intermolecular C-H silylation initiated by aminopalladation

Ji, Xiaoming,Wei, Feng,Wan, Bin,Cheng, Cang,Zhang, Yanghui

supporting information, p. 7801 - 7804 (2020/07/27)

A Pd(ii)-catalyzed intermolecular C-H silylation reaction initiated by aminopalladation has been developed. The C-H bonds were activated by an alkyl Pd(ii) species generated through aminopalladation and then disilylated with hexamethyldisilane to form disilylated indolines as the final products. The reaction provides a new method for the introduction of silyl groups into complex organic molecules.
