Check Digit Verification of cas no

The CAS Registry Mumber 753441-74-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,3,4,4 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 753441-74:
(8*7)+(7*5)+(6*3)+(5*4)+(4*4)+(3*1)+(2*7)+(1*4)=166
166 % 10 = 6
So 753441-74-6 is a valid CAS Registry Number.

A High-Yield and Cost-Effective Synthesis of Spirotetramat

Mao, Longfei,Wang, Jiahao,Xu, Guiqing,Zhou, Yingjie

, p. 1775 - 1778 (2020/12/01)

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.
