Check Digit Verification of cas no
The CAS Registry Mumber 66644-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,4 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66644-80:
(7*6)+(6*6)+(5*6)+(4*4)+(3*4)+(2*8)+(1*0)=152
152 % 10 = 2
So 66644-80-2 is a valid CAS Registry Number.

, (2020/05/01)
The invention discloses a novel preparation method of 2,3-dimethoxy-5-sulfonamide benzoic acid, which relates to a preparation method of a medical intermediate. The method sequentially comprises the following steps: taking 3, 4-dihydroxybenzenesulfonamide as a raw material; performing bromination and substitution reactions in sequence; and finally, carrying out hydrolysis twice to obtain the product 2,3-dimethoxy-5-sulfonamide benzoic acid. The invention provides a brand-new synthetic route, the used raw materials are wide and sufficient in source, low in price, mild in reaction condition andsimple in process, the reaction of each step is conventionally operated, the use of highly toxic dimethyl sulfate and other harmful raw materials is avoided, the pollution is reduced, and the method has a relatively good application range.
