124770-04-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124770-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,7 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124770-04:
(8*1)+(7*2)+(6*4)+(5*7)+(4*7)+(3*0)+(2*0)+(1*4)=113
113 % 10 = 3
So 124770-04-3 is a valid CAS Registry Number.

SYNTHESIS OF PROPELLANES BY "EXOCYCLIC" TRANSANNULAR CYCLOADDITION OF OLEFINIC METHYLENECYCLOPROPANES
Yamago, Shigeru,Nakamura, Eiichi
, p. 3081 - 3088 (1989)
Olefinic methylenecyclopropanes undergo quantitative transannular ring closure under Group 10 metal catalysis to give propellanes through cycloaddition of trimethylenemethane-like intermediate.
