215025-42-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215025-42-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,0,2 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 215025-42:
(8*2)+(7*1)+(6*5)+(5*0)+(4*2)+(3*5)+(2*4)+(1*2)=86
86 % 10 = 6
So 215025-42-6 is a valid CAS Registry Number.

A novel route to the geissoschizine skeleton: The influence of ligands on the diastereoselectivity of the heck cyclization
Birman, Vladimir B.,Rawal, Viresh H.
, p. 7219 - 7222 (1998)
A concise, novel route to the geissoschizine skeleton has been developed. The key step involves a Heck cyclization reaction, which was found to lead to opposite diastereomers, (±)-8 or (±)-9, depending on the reaction conditions.
