Check Digit Verification of cas no

The CAS Registry Mumber 1384186-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,1,8 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1384186-75:
(9*1)+(8*3)+(7*8)+(6*4)+(5*1)+(4*8)+(3*6)+(2*7)+(1*5)=187
187 % 10 = 7
So 1384186-75-7 is a valid CAS Registry Number.

Synthesis of isoquinoline alkaloids via oxidative amidation-bischler- napieralski reaction

Shankar,More, Satish S.,Madhubabu,Vembu,Syam Kumar

, p. 1013 - 1020 (2012)

A straightforward synthesis of -keto amides by coupling primary amines with aryl dibromoethanones under oxidative amidation conditions has been developed. The -keto amides were then subjected to heterocyclodehydration reaction under Bischler-Napieralski conditions followed by aromatization with DBU provided 1-benzoyl isoquinolines in a two-stage process. Utilizing this methodology, isoquinoline alkaloids such as thalmicrinone, papavaraldine, and pulcheotine A were synthesized in excellent yields. Georg Thieme Verlag Stuttgart · New York.
