18351-33-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18351-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,5 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18351-33:
(7*1)+(6*8)+(5*3)+(4*5)+(3*1)+(2*3)+(1*3)=102
102 % 10 = 2
So 18351-33-2 is a valid CAS Registry Number.

Palladium-catalyzed ortho-alkenylation of aryl hydrogen phosphates using a new mono-phosphoric acid directing group

Chan, Li Yan,Kim, Sunggak,Ryu, Taekyu,Lee, Phil Ho

supporting information, p. 4682 - 4684 (2013/06/04)

A highly efficient Pd-catalyzed ortho-alkenylation is reported using a mono-phosphoric acid-directing group for the first time. This phosphoric acid-directing group is successfully utilized for the synthesis of various alkenylated products and offers a new approach to transition-metal-catalyzed C-H activation.
