39907-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39907-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39907-99:
(7*3)+(6*9)+(5*9)+(4*0)+(3*7)+(2*9)+(1*9)=168
168 % 10 = 8
So 39907-99-8 is a valid CAS Registry Number.

Transformation of cyclohexene to enantiopure cyclitols mediated by sequential oxyselenenylation with (S,S)-hydrobenzoin: Synthesis of D-chiro-inositol and muco-quercitol

Kim, Kwan Soo,Park, Jong H.,Moon, Hoi Kyung,Yi, Hann

, p. 1945 - 1946 (2007/10/03)

Oxyselenenylation of cyclohexene with (S,S)-hydrobenzoin and subsequent oxidation-elimination allows isolation of an allylic ether in which further phenylselenenylation is completely regioselective, thus allowing entry to the cyclitols D-chiro-inositol and muco-quercitol.
