Check Digit Verification of cas no
The CAS Registry Mumber 119102-24-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,0 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119102-24:
(8*1)+(7*1)+(6*9)+(5*1)+(4*0)+(3*2)+(2*2)+(1*4)=88
88 % 10 = 8
So 119102-24-8 is a valid CAS Registry Number.

Synthesis of ethyl 1-azabicyclo[2.2.1]hept-4-yl carboxylate
Orlek,Wadsworth,Wyman,King
, p. 1245 - 1246 (1991)
The dipolar cycloaddition reaction of α-methylene butyrolactone and N-benzyl azomethine ylid (5) affords the spirolactone (2) which rearranges to give ethyl 1-azabicyclo[2.2.1]hept-4-yl carboxylate (1) in excellent overall yield.
