140709-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140709-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,7,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140709-72:
(8*1)+(7*4)+(6*0)+(5*7)+(4*0)+(3*9)+(2*7)+(1*2)=114
114 % 10 = 4
So 140709-72-4 is a valid CAS Registry Number.

, p. 395 - 398 (2007/10/02)
A stereoselective synthesis of trans-decalins has been developed by use of regiocontrolled 6-endo-trig-radical cyclization of alkenyl bromides with an exo-methylene group in cyclohexane ring.
