Check Digit Verification of cas no
The CAS Registry Mumber 113502-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,0 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113502-31:
(8*1)+(7*1)+(6*3)+(5*5)+(4*0)+(3*2)+(2*3)+(1*1)=71
71 % 10 = 1
So 113502-31-1 is a valid CAS Registry Number.

FLASH VACUUM THERMOLYSIS OF OXAZOLIDINES : A NEW WAY TO REACTIVE AZOMETHINE YLIDES. REGIO AND STEREOSPECIFIC SYNTHESIS OF SUBSTITUTED PYRROLIDINES.
Joucla, Marc,Mortier, Jacques
, p. 2973 - 2974 (2007/10/02)
Flash vacuum thermolysis of oxazolidines leads to azomethine ylides trapped by an intramolecular 1,3-dipolar cycloaddition reaction which occured only in the gas phase.
