155267-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155267-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,2,6 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 155267-05:
(8*1)+(7*5)+(6*5)+(5*2)+(4*6)+(3*7)+(2*0)+(1*5)=133
133 % 10 = 3
So 155267-05-3 is a valid CAS Registry Number.

A new stereoselective synthesis of ladybug defence alkaloid precoccinelline
Yue,Nicolay,Royer,Husson
, p. 3139 - 3148 (2007/10/02)
We have accomplished a new stereoselective synthesis of precoccinelline 1 in six steps from the chiral synthon 6 with a overall yield of 31%. The main feature of this synthesis is the asymmetric synthesis of the trans 2,6-keto- acetal piperidine 14 which
