1642-48-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1642-48-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1642-48:
(6*1)+(5*6)+(4*4)+(3*2)+(2*4)+(1*8)=74
74 % 10 = 4
So 1642-48-4 is a valid CAS Registry Number.

DIALKYL(TRIMETHYLSILYL)TETRATHIOPHOSPHATES IN SYNTHESIS OF SUBSTITUTED TETRATHIOPHOSPHATES

Nizamov, Il'Yas S.,Kuznetzov, Vladislav A.,Batyeva, Elvira S.

, p. 249 - 258 (2007/10/02)

Reactions of S,S'-dialkyl-S''-trimethylsilyl tetrathiophosphates with aldehydes, acetals, ortho ethers, aminals, thioacetals, bis(thiocyanato)methane, disulfides and alkyl halides resulted in the products of tetrathiophosphate structure.Key words: S,S'-Dialkyl-S''-trimethylsilyl tetrathiophosphates; organic substances; substituted tetrathiophosphates.

DIALKYL TRIMETHYLSILYL TETRATHIOPHOSPHATES. SYNTHESIS AND TRANSFORMATIONS

Nizamov, I.S.,Kuznetsov, V.A.,Batyeva, E.S.,Al'fonsov, V.A.

, p. 1196 - 1198 (2007/10/02)

We have developed an efficient method for synthesizing dialkyl trimethylsilyl tetrathiophosphates, which react with aldehydes, acetals, ortho esters, thioacetals, bis(thiocyanato)methane, diethyl disulfide, and alkyl halides to give a number of new tetrathiophosphate derivatives.
