Check Digit Verification of cas no

The CAS Registry Mumber 1258206-71-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,0 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1258206-71:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*0)+(3*6)+(2*7)+(1*1)=151
151 % 10 = 1
So 1258206-71-1 is a valid CAS Registry Number.

Efficient carboazidation of alkenes using a radical desulfonylative azide transfer process

Weidner, Karin,Giroult, Andre,Panchaud, Philippe,Renaud, Philippe

, p. 17511 - 17515 (2010)

The radical-mediated carboazidation of terminal alkenes using electrophilic alkanesulfonyl azides is reported. A single reagent delivers the necessary electrophilic alkyl radical as well as the azido group, and good yields are obtained by using a moderate excess of the carboazidating reagent (1.5-2 equiv). Interestingly, in addition to the starting sulfonyl azide, this method requires only the use of a radical initiator, di-tert-butyldiazene. In terms of atom economy, this azide transfer reaction is close to ideal, as SO2 (1 equiv) is the only side product. The synthetic potential of this process has been demonstrated by a formal synthesis of the alkaloid lepadiformine C.
