Check Digit Verification of cas no

The CAS Registry Mumber 215026-14-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,0,2 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 215026-14:
(8*2)+(7*1)+(6*5)+(5*0)+(4*2)+(3*6)+(2*1)+(1*4)=85
85 % 10 = 5
So 215026-14-5 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 (1998)

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.
