690982-19-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 690982-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,9,8 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 690982-19:
(8*6)+(7*9)+(6*0)+(5*9)+(4*8)+(3*2)+(2*1)+(1*9)=205
205 % 10 = 5
So 690982-19-5 is a valid CAS Registry Number.

Termination of Mn(III)-based oxidative cyclizations by trapping with azide
Snider, Barry B.,Duvall, Jeremy R.
, p. 1265 - 1268 (2007/10/03)
The radicals formed in Mn(III)-based oxidative free-radical cyclizations of β-keto esters and malonate esters can be trapped with sodium azide and Mn(III) to give cyclic and bicyclic azides in 30-80% yield. Reduction of the azide gives bi- and tricyclic l
