Check Digit Verification of cas no

The CAS Registry Mumber 109988-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,8 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109988-18:
(8*1)+(7*0)+(6*9)+(5*9)+(4*8)+(3*8)+(2*1)+(1*8)=173
173 % 10 = 3
So 109988-18-3 is a valid CAS Registry Number.

Chlorotrithioperformates - a New Class of Compounds. Preparation and Some Applications

Moltzen, Ejner K.,Jensen, Birgit,Senning, Alexander

, p. 609 - 618 (2007/10/02)

The α additions of thiosulfenyl chlorides to carbon monosulfide (CS) constitute a general route to compounds containing the so far inaccessible functional group ClC(S)SS.Four examples are presented, CH3C(O)-, ClC(O)-, Cl3C-, and Cl5C2-SSC(S)Cl, all of which were prepared in good yields.The versatility of this new class of compounds as synthetic precursors is demonstrated by chlorination of the thiocarbonyl groups to the corresponding new α,α-dichloroalkanesulfenyl chlorides.The preparation of several derivatives of these sulfenyl chlorides is described.Considering the variety of thiosulfenyl chlorides available, a large group of new compounds has become accessible via this synthetic pathway.
