Check Digit Verification of cas no
The CAS Registry Mumber 955-16-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 955-16:
(5*9)+(4*5)+(3*5)+(2*1)+(1*6)=88
88 % 10 = 8
So 955-16-8 is a valid CAS Registry Number.

Main pathways arc established of catalytic oxidative transformations of 3,4-di- and 3,3',4,4'-tetramethylbiphenyls in vapor phase. The possibility is analyzed of obtaining the corresponding anhydrides, imides, and nitriles of biphenylcarboxylic acids in yields of up to 59-69%.
Ashless additives for lubricating compositions

, (2008/06/13)
Superior ashless additives for lubricants are prepared by a process comprising first introducing a petroleum sulfonic acid and a polyamine to a reaction zone and subsequently introducing a cyclic anhydride of a dicarboxylic acid into the reaction zone. In another embodiment, the solids content of the additives is reduced to acceptable levels by removal of free SO2 from the petroleum sulfonic acid prior to preparing the additive. Lubricating oil compositions containing these ashless additives are also provided.
