Check Digit Verification of cas no
The CAS Registry Mumber 39925-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,2 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 39925-38:
(7*3)+(6*9)+(5*9)+(4*2)+(3*5)+(2*3)+(1*8)=157
157 % 10 = 7
So 39925-38-7 is a valid CAS Registry Number.

An enantioselective allylation reaction of allylic carbonates with sodium sulfite (Na2SO3) catalyzed by Ir complex was accomplished, providing allylic sulfonic acids in good to excellent yields with a high level of enantioand regioselectivities. (R)-2-Phenyl-2-sulfoacetic acid, a key intermediate for the synthesis of Cefsulodin and Sulbenicillin, was synthesized as well.

The invention discloses a preparation method of sulbenicillin sodium. According to the invention, L-amino acid is firstly adopted to perform splitting on D, L-sulfonylphenylacetic acid to obtain D(-)-sulfonylphenylacetic acid, then D(-)-sulfonylphenylacetic acid is compounded with D, L-sulfonylphenylacetic acid to prepare a sulfonylphenylacetic acid mixture with D(-)-sulfonylphenylacetic acid to L(+)-sulfonylphenylacetic acid ratio being about 78%:22%, the sulfonylphenylacetic acid mixture is chlorinated and then reacts with 6-APA, and then reacts with sodium iso-octoate, to directly obtain asulbenicillin sodium mixture with the ratio of D(-)-sulbenicillin sodium to L(+)-sulbenicillin sodium being about 78%:22%. According to the invention, post-treatment process is simplified, no water isused in the step of producing sulbenicillin sodium, hydrolysis impurity level is reduced, product purity is more than 99.0%, and product mole rate is more than 90%.
