Check Digit Verification of cas no

The CAS Registry Mumber 97023-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,0,2 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97023-15:
(7*9)+(6*7)+(5*0)+(4*2)+(3*3)+(2*1)+(1*5)=129
129 % 10 = 9
So 97023-15-9 is a valid CAS Registry Number.

A boron-based synthesis of the natural product (+)-trans- dihydrolycoricidine

Poe, Sarah L.,Morken, James P.

, p. 4189 - 4192 (2011/06/20)

Diastereoselective diboration results in the highly selective 1,4-dihydroxylation of chiral cyclohexadienes (see scheme). Together with the catalytic enantioselective conjugate allylboration, the diene diboration facilitates the asymmetric synthesis of the cytotoxic agent (+)-trans- dihydrolycoricidine (1). pin=pinacol.
