Check Digit Verification of cas no

The CAS Registry Mumber 140225-67-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,2 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140225-67:
(8*1)+(7*4)+(6*0)+(5*2)+(4*2)+(3*5)+(2*6)+(1*7)=88
88 % 10 = 8
So 140225-67-8 is a valid CAS Registry Number.

INFRARED MATRIX ISOLATION STUDIES OF THE REACTIONS OF F2 WITH SULFUR AND PHOSPHORUS BASES

Machara, Nicholas P.,Ault, Bruce S.

, p. 129 - 138 (1988)

The matrix isolation technique has been used to study the initial intermediate products of the reaction of molecular fluorine, F2, with several alkyl sulfides, as well as with trimethylphosphine.While previous studies of the reaction of these bases with ClF and Cl2 demonstrated that charge transfer complexes are formed, no evidence has been observed here for complex formation.Rather direct reaction occurs for each system studied, leading in several cases to hydrogen displacement products, while in other systems the spectral evidence supports a direct addition reaction.For example, in the F2/H2S system, initial formation of H2SF2 is postulated, followed by HF elimination to form HSF upon Hg arc irradiation.
