1800-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1800-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1800-81:
(6*1)+(5*8)+(4*0)+(3*0)+(2*8)+(1*1)=63
63 % 10 = 3
So 1800-81-3 is a valid CAS Registry Number.

Vibrational Excitation of the Reaction between Vinyl Bromide and Fluorine in Solid Argon

Cesaro, Stella Nunziante,Frei, Heinz,Pimentel, George C.

, p. 2142 - 2147 (1983)

A number of unsuccessful attempts to induce bimolecular addition reactions with selective vibrational excitation in cryogenic solids are reported here: 1,3-butadiene with Cl2, ClF, Br2, I2, and XeF2; vinyl chloride with F2.One system, vinyl bromide with fluorine in solid argon, did respond by showing reaction product growth upon laser excitation at 3116, 3098, 1849, 1808, and 1605 cm-1.Identification of reaction products suggests F2 addition across the double bond followed significantly by HF elimination but apparently without HBr elimination.Relative quantum yields display a monotonic dependence upon photon energy that is even more dramatic than that found earlier for the ethylene-fluorine reaction.Thus excitation of the C-H stretching modes either at 3116 or 3098 cm-1 is 102 times more effective than excitation at 1849 or 1848 cm-1 and 103 times more effective than at 1605 cm-1.
