Check Digit Verification of cas no

The CAS Registry Mumber 143582-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,8 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143582-92:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*2)+(2*9)+(1*2)=137
137 % 10 = 7
So 143582-92-7 is a valid CAS Registry Number.

A convenient synthesis of trifluoromethyl ethers by oxidative desulfurization-fluorination of dithiocarbonates

Kanie, Kiyoshi,Tanaka, Yoichiro,Suzuki, Kazundo,Kuroboshi, Manabu,Hiyama, Tamejiro

, p. 471 - 484 (2007/10/03)

Trifluoromethyl ethers R-OCF3 are easily synthesized from the corresponding dithiocarbonates R-OCS2Me (R = aryl or primary alkyl) by a reagent system consisting of 70% HF/pyridine and an N-halo imide. When the reaction is applied to R-OCS2Me wherein R = secondary alkyl, tertiary alkyl, or benzylic group, fluorination leading to the corresponding alkyl fluorides R-F is achieved, whereas a combination of 50% HF/pyridine and N- bromosuccinimide affords the corresponding trifluoromethyl ethers R-OCF3 (R = secondary).
