1372789-09-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1372789-09-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,7,8 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1372789-09:
(9*1)+(8*3)+(7*7)+(6*2)+(5*7)+(4*8)+(3*9)+(2*0)+(1*9)=197
197 % 10 = 7
So 1372789-09-7 is a valid CAS Registry Number.

The first total synthesis of gravicycle
Ueda, Katsuaki,Sato, Itaru,Hirama, Masahiro
, p. 87 - 89 (2012)
The total synthesis of gravicycle, isolated from Grevillea robusta, has been achieved for the first time. The key step of our synthetic process is the efficient assembly of a highly functionalized biaryl ether via the copper-catalyzed O-arylation of suita
