75767-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75767-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,6 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75767-72:
(7*7)+(6*5)+(5*7)+(4*6)+(3*7)+(2*7)+(1*2)=175
175 % 10 = 5
So 75767-72-5 is a valid CAS Registry Number.

Total Synthesis of (-)-Prezizaene and (-)-Prezizanol
Vettel, Paula Roach,Coates, Robert M.
, p. 5430 - 5432 (2007/10/02)
An 18-step total synthesis of the novel zizaane sesquiterpenes, (-)-prezizaene (1) and (-)-prezizanol (2), from (+)-pulegone is described; the key step of the synthesis is the intramolecular ring expansion of (diazoethyl)hydrindanone 12 to the isomeric me
