688-62-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 688-62-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 688-62:
(5*6)+(4*8)+(3*8)+(2*6)+(1*2)=100
100 % 10 = 0
So 688-62-0 is a valid CAS Registry Number.

Synthesis of mixed phosphorotrithioates from white phosphorus

supporting information, p. 8353 - 8359 (2020/12/29)

The first general and high-yielding synthesis of mixed phosphorotrithioates (R1S)2P(O)SR2 involving white phosphorus, disulfides, and alkyl halides is presented, which provides the shortest and environmentally benign method to synthesize these compounds of practical importance. Only one method for the formation of (R1S)2P(O)SR2 from elemental phosphorus has been developed. Here, with the use of KOH as a base and DMSO-toluene as a solvent, various disulfides couple readily with white phosphorus to give O-potassium S,S-dialkylphosphorotrithioates (R1S)2P(S)OK in almost quantitative yields, which react with alkyl halides to form (R1S)2P(O)SR2 in high yields. The reaction is characterized by the complete conversion of white phosphorus. Moreover, this method can be easily adapted to large-scale preparation. Our mechanistic data suggest that the attack of RSK on S,S,S-trialkyl phosphorotrithioates and subsequent C-S bond cleavage, the Michaelis-Arbuzov-like dealkylation, are the key steps in the formation of (R1S)2P(S)OK.
