138291-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138291-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138291-45:
(8*1)+(7*3)+(6*8)+(5*2)+(4*9)+(3*1)+(2*4)+(1*5)=139
139 % 10 = 9
So 138291-45-9 is a valid CAS Registry Number.

Arylation of camphene with arenediazonium salts catalyzed by palladium acetate
Yong,Yi,Zhuangyu,Hongwen
, p. 967 - 969 (2007/10/02)
(E)-8-Arylcamphenes 3 were obtained in moderate to good yields by the reaction of camphene (1) with a variety of arenediazonium tetrafluoroborates 2 in the presence of palladium acetate under mild conditions. The E-configuration of the products was confir
