Check Digit Verification of cas no
The CAS Registry Mumber 203312-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,1 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 203312-38:
(8*2)+(7*0)+(6*3)+(5*3)+(4*1)+(3*2)+(2*3)+(1*8)=73
73 % 10 = 3
So 203312-38-3 is a valid CAS Registry Number.

Abstract: cis-8-Methoxy-1,3-diazaspiro[4.5]decane-2,4-dione, the key intermediate in the synthesis of spirotetramat, was synthesized by catalytic hydrogenation, oxidation, and Bucherer–Bergs reaction with 4-methoxycyclohexan-1-one as raw material. Spirotetramat was obtained in an overall yield of 20.4% by a multi-step reaction sequence including hydrolysis, esterification, acylation, intramolecular condensation, and O-acylation. The advantages of the proposed method are mild conditions, simple operation, and good to excellent yields in each step.
