308274-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 308274-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,2,7 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 308274-40:
(8*3)+(7*0)+(6*8)+(5*2)+(4*7)+(3*4)+(2*4)+(1*0)=130
130 % 10 = 0
So 308274-40-0 is a valid CAS Registry Number.

Intramolecular iron(II)-catalyzed addition reactions of propargyloxycarbonyl azides
Bach,Schlummer,Harms
, p. 1330 - 1332 (2007/10/03)
The Fe(II)-catalyzed dediazotation of the propargyl-oxycarbonyl azides 2-4 was studied. In the case of phenyl- (2) and n-butyl-substituted (3) alkynes the products 5 and 6 of an intramolecular syn-aminochlorination were isolated in excellent yields (81-99
