142439-13-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142439-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,3 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142439-13:
(8*1)+(7*4)+(6*2)+(5*4)+(4*3)+(3*9)+(2*1)+(1*3)=112
112 % 10 = 2
So 142439-13-2 is a valid CAS Registry Number.

Catalytic and photolytic reactions of 5,6,7,8-tetrahydroindolizines with oxygen
Ming, De Wang,Alper, Howard
, p. 6855 - 6858 (1995)
The Co2(CO)8 catalyzed reaction of 2-aryl-5,6,7,8-tetrahydroindolizines with oxygen gave the corresponding 8a-hydroxy-6,7,8,8a-tetrahydro-3(5H)indolizinones in good yield; the same transformation occurred by photolysis in the absence
