19967-24-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19967-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,6 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19967-24:
(7*1)+(6*9)+(5*9)+(4*6)+(3*7)+(2*2)+(1*4)=159
159 % 10 = 9
So 19967-24-9 is a valid CAS Registry Number.

Palladium-catalyzed double-bond migration of unsaturated hydrocarbons accelerated by tantalum chloride

Murai, Masahito,Nishimura, Kengo,Takai, Kazuhiko

supporting information, p. 2769 - 2772 (2019/03/23)

The operationally simple palladium-catalyzed double-bond migration without heteroatom-containing coordinating functional groups is described. Addition of TaCl5 as a second catalyst greatly enhanced the migration efficiency to provide β-alkylsty
