Check Digit Verification of cas no
The CAS Registry Mumber 1001756-09-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,1,7,5 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1001756-09:
(9*1)+(8*0)+(7*0)+(6*1)+(5*7)+(4*5)+(3*6)+(2*0)+(1*9)=97
97 % 10 = 7
So 1001756-09-7 is a valid CAS Registry Number.

Synthetic method of naphthaquinone sulfonyl chloride
-
Paragraph 0030, (2017/01/12)
The invention discloses a synthetic method of naphthaquinone sulfonyl chloride, belonging to the technical field of organic synthesis. According to the synthetic method, naphthaquinone sulfonyl chloride is synthesized from naphthaquinone sulfonyl chloride in an inert solvent in the presence of a catalysis amount of initiator by taking di(trichloromethyl)carbonic ester as an acylating chlorination reagent. Highly corrosive materials such as chlorosulfonic acid, thionyl chloride and the like are not used in the reaction process, and a large number of sulfur dioxide, hydrogen chloride gas and acid wastewater are not generated in the reaction, so that the treating stresses of water gas and wastewater are relieved, the environment is protected, the corrosion resistance requirement of industrial equipment is reduced, and the safe operation of the equipment is guaranteed.
