93777-44-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93777-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,7 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93777-44:
(7*9)+(6*3)+(5*7)+(4*7)+(3*7)+(2*4)+(1*4)=177
177 % 10 = 7
So 93777-44-7 is a valid CAS Registry Number.

CATIONIC CYCLIZATION OF LINALYL- AND GERANYL/NERYLACETIC ACID. A FACILE ENTRY TO THE BREXANE SYSTEM

Calcium(II)- And Triflimide-Catalyzed Intramolecular Hydroacyloxylation of Unactivated Alkenes in Hexafluoroisopropanol

Qi, Chenxiao,Yang, Shengwen,Gandon, Vincent,Leb?uf, David

supporting information, p. 7405 - 7409 (2019/10/02)

We report an efficient intramolecular hydroacyloxylation of unactivated alkenes, offering a streamlined access to relevant γ-lactones, which features the utilization of either a calcium(II) salt or triflimide as a catalyst in hexafluoroisopropanol. This method could be applied to the synthesis of natural products and the late-stage functionalization of natural and bioactive molecules. Additionally, DFT computations were used to elucidate the twist of reactivity observed between the hydroamidation and hydroacyloxylation of unactivated alkenes regarding the formation of 5- and 6-membered rings.
