Check Digit Verification of cas no

The CAS Registry Mumber 871331-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,3,3 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 871331-87:
(8*8)+(7*7)+(6*1)+(5*3)+(4*3)+(3*1)+(2*8)+(1*7)=172
172 % 10 = 2
So 871331-87-2 is a valid CAS Registry Number.

Carbenoid addition to phenols to give cycloheptatrienols. Stereochemical regulation and ligand-dependent switching of chemoselectivity

Im, Chun Young,Okuyama, Tadashi,Sugimura, Takashi

, p. 314 - 315 (2007)

Cycloheptatrienols were prepared stereoselectively by the intramolecular Buechner reaction of phenols using a 2,4-pentane-diol tether of suitable stereochemistry, where the intrinsically favorable O-H insertion is effectively suppressed. Copyright
