1283147-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1283147-55-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,1,4 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1283147-55:
(9*1)+(8*2)+(7*8)+(6*3)+(5*1)+(4*4)+(3*7)+(2*5)+(1*5)=156
156 % 10 = 6
So 1283147-55-6 is a valid CAS Registry Number.

Highly convergent total synthesis of (+)-lithospermic acid via a late-stage intermolecular C-H olefination
Wang, Dong-Hui,Yu, Jin-Quan
, p. 5767 - 5769 (2011/06/22)
The total synthesis of (+)-lithospermic acid is reported, which exploits two successive C-H activation reactions as key steps. Rh-catalyzed carbene C-H insertion reaction utilizing Davies's catalyst was used to forge dihydrobenzofuran core, and a late-sta
