350031-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 350031-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,0,3 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 350031-71:
(8*3)+(7*5)+(6*0)+(5*0)+(4*3)+(3*1)+(2*7)+(1*1)=89
89 % 10 = 9
So 350031-71-9 is a valid CAS Registry Number.

Diastereoselective cobalt-mediated acylation-cyclization of allenes
Bates,Satcharoen
, p. 532 - 534 (2007/10/03)
Allenes with α-oxygen and γ-sulfonamide substituents were synthesized and cyclized to pyrrolidines using an acyl cobalt reagent. The reactions proceeded with very high trans selectivity.
