Check Digit Verification of cas no
The CAS Registry Mumber 33798-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33798-77:
(7*3)+(6*3)+(5*7)+(4*9)+(3*8)+(2*7)+(1*7)=155
155 % 10 = 5
So 33798-77-5 is a valid CAS Registry Number.

Investigation on recovery of p-mephso3k based on solid-liquid equilibrium of the p-mephso3k-k2co3-h2o system
Shuanghong, Hao,Jie, Xu,Mengqi, Chen,Yan, Wei
, p. 1249 - 1254 (2021)
In this article, we propose a method of recovering p-MePhSO3K from the industrial by-product of quizalofop-p-ethyl. The phase diagram of the solid-liquid equilibrium system of p-MePhSO3K2CO3-H2O at the temperatures of 15, 25, 35, 45, and 55°C was determined and plotted. Based on the phase diagram of 25°C, the separation and recovery process of p-MePhSO3K from the p-MePhSO3K2CO3-H2O system was designed by analyzing the crystallization fields. First, p-MePhSO3K and K2CO3 were crystallized from wastewater in turn through evaporation separation. Then, the crystallized p-MePhSO3K was purified further by washing with ethanol. Finally, the pure p-MePhSO3K was transformed into the intermediate p-toluenesulfonyl chloride and then the intermediate L-p-toluenesulfonate ethyl lactate for quizalofop-p-ethyl production.
