Check Digit Verification of cas no

The CAS Registry Mumber 1809-75-2 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 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1809-75:
(6*1)+(5*8)+(4*0)+(3*9)+(2*7)+(1*5)=92
92 % 10 = 2
So 1809-75-2 is a valid CAS Registry Number.

Dichlorocarbene from Flash Vacuum Pyrolysis of Trimethyl(trichloromethyl)silane. Possible Observation of 1,1-Dichloro-3-Phenyl Carbonyl Ylide

Gisch, John F.,Landgrebe, John A.

, p. 2050 - 2054 (1985)

Flash vacuum pyrolysis of trimethyl(trichloromethyl)silane 3 at 500-700 deg C was shown to be a simple and efficient method for the production of :CCl2 in the gas phase.The copyrolysis of silane 3 and benzaldehyde (7) at 600 deg C led to 1,1,1-trichloro-2-phenyl-2-(trimethylsiloxy)ethane (8), a 1:1 adduct, in addition to benzal chloride (15) and α-chlorophenylacetyl chloride (16), product thought to arise from 1,1-dichloro-3-phenyl carbonyl ylide 17 as outlined in Scheme I.An orange-red material trapped at deg K could be photobleached as well as thermally bleached and had an IR band at 1650 cm-1 and a si gnificant absorption with λmax 510 nm (and a broad shoulder at a 580 nm).
