31909-46-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31909-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,9,0 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31909-46:
(7*3)+(6*1)+(5*9)+(4*0)+(3*9)+(2*4)+(1*6)=113
113 % 10 = 3
So 31909-46-3 is a valid CAS Registry Number.

Synthesis of sym-(E/Z)-Diselenadithiafulvalene

Lakshmikantham, M.V.,Cava, Michael P.

, p. 2632 - 2636 (1980)

sym-Diselenadithiafulvalene (3) has been synthesized as an inseparable E,Z isomer mixture by two fundamentally different routes.The first synthesis proceeds via ethylene diselenocyanate (9), ethane-1,2-diselenol (8), 1,3-Diselenolane-2-thione (7), 4,5-bis(carbomethoxy)-1,3-thiaselenole-2-selone (12),and tetrakis(carbomethoxy)-sym-diselenadithiafulvalene (13).The second synthesis,which involves a greatly improved route to 1,3-thiaselenole-2-selone (18),provides the most practical method available for the preparation of larger quantities of 3.
