Check Digit Verification of cas no

The CAS Registry Mumber 1362100-28-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,2,1,0 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1362100-28:
(9*1)+(8*3)+(7*6)+(6*2)+(5*1)+(4*0)+(3*0)+(2*2)+(1*8)=104
104 % 10 = 4
So 1362100-28-4 is a valid CAS Registry Number.

Dehydrative fragmentation of 5-hydroxyalkyl-1 h -tetrazoles: A mild route to alkylidenecarbenes

Wardrop, Duncan J.,Komenda, John P.

, p. 1548 - 1551 (2012/06/05)

The development of a mild, base-free method for the generation of alkylidenecarbenes is reported. Treatment of 5-hydroxyalkyl-1H-tetrazoles with carbodiimides generates products arising from the 1,2-rearrangement or [1,5]-C-H bond insertion of a putative alkylidenecarbene. Formation of this divalent intermediate is proposed to occur by way of a tetraazafulvene, which undergoes extrusion of 2 mol of dinitrogen. Details of this methodology, its application to the synthesis of combretastatin A-4, and an improved route to 5-hydroxyalkyl-1H-tetrazoles are described.
