128855-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128855-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,5 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128855-21:
(8*1)+(7*2)+(6*8)+(5*8)+(4*5)+(3*5)+(2*2)+(1*1)=150
150 % 10 = 0
So 128855-21-0 is a valid CAS Registry Number.

An asymmetric synthesis of the ant venom alkaloid (3S,5S,8aR)-3-butyl-5-(4-pentenyl)indolizidine via the sharpless asymmetric dihydroxylation
Takahata, Hiroki,Bandoh, Hiroshi,Momose, Takefumi
, p. 39 - 42 (1996)
The first asymmetric synthesis of the ant venom alkaloid (3S,5S,8aR)-3-butyl-5-(4-pentenyl)indolizidine (1) has been performed by starting with the Sharpless asymmetric dihydroxylation of N- alkenylcarbamate (3) followed by reductive annulation (5-exotetr
