882880-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 882880-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,2,8,8 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 882880-68:
(8*8)+(7*8)+(6*2)+(5*8)+(4*8)+(3*0)+(2*6)+(1*8)=224
224 % 10 = 4
So 882880-68-4 is a valid CAS Registry Number.

Concise enantiospecific synthesis of (+)-calvine
Dewi-Wülfing, Purnama,Gebauer, Julian,Blechert, Siegfried
, p. 487 - 489 (2006)
We report herein an efficient enantiospecific synthesis of (+)-calvine in nine steps from (R)-epichlorohydrine. The convergent synthesis is based on an olefin cross-metathesis (CM) reaction of a chiral homoallylamine and an enone. Subsequent reductive cyc
