158413-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158413-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,4,1 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 158413-47:
(8*1)+(7*5)+(6*8)+(5*4)+(4*1)+(3*3)+(2*4)+(1*7)=139
139 % 10 = 9
So 158413-47-9 is a valid CAS Registry Number.

Formal total synthesis of (-)-dendrobine using zirconium-promoted reductive cyclization
Uesaka,Saitoh,Mori,Shibasaki,Okamura,Date
, p. 5633 - 5642 (2007/10/02)
The alkaloid (-)-dendrobine was synthesized from (+)-calvone by a short sequence using zirconium-promoted reductive cyclization. The absolute configuration of a synthetic intermediate was determined by an improved version of Mosher's method.
