141521-15-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141521-15-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,5,2 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141521-15:
(8*1)+(7*4)+(6*1)+(5*5)+(4*2)+(3*1)+(2*1)+(1*5)=85
85 % 10 = 5
So 141521-15-5 is a valid CAS Registry Number.

, p. 443 - 446 (1992)
A possible chiral synthetic route to the alkaloid (-)-dendrobine has been explored by employing intramolecular Pauson-Khand reaction as the key step.The cobalt complex generated from (S)-carvone yielded a single stereoisomer (10) on intramolecular Pauson-
