139236-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139236-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,3 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139236-72:
(8*1)+(7*3)+(6*9)+(5*2)+(4*3)+(3*6)+(2*7)+(1*2)=139
139 % 10 = 9
So 139236-72-9 is a valid CAS Registry Number.

A radical-based synthesis of (Z,Z)-tricyclohexaprenol
Heissler,Jenn,Nagano
, p. 7587 - 7590 (2007/10/02)
Addition of the isocopal-12-15-yl radical to a methyl 3-hydroxy-2-methylene alkenoate and stereoselective elimination of methanesulphonic acid from the mesylated adducts are the key steps of this synthesis of (Z,Z)-tricyclohexaprenol.
