Check Digit Verification of cas no

The CAS Registry Mumber 164651-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,6,5 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 164651-65:
(8*1)+(7*6)+(6*4)+(5*6)+(4*5)+(3*1)+(2*6)+(1*5)=144
144 % 10 = 4
So 164651-65-4 is a valid CAS Registry Number.

Regiochemical control of the ring opening of 1,2-epoxides by means of chelating processes. 9. Synthesis and ring opening reactions of cis- and trans-oxides derived from 3-(benzyloxymethyl)cyclopentene and methyl 2- cyclopenten-1-carboxylate

, p. 8089 - 8112 (1995)

The regiochemical outcome of the ring opening of 1,2-epoxides through chelation processes assisted by metal ions, was verified in the oxirane systems derived from cyclopentene bearing a polar functionality (CH2OBn or COOMe) in a homoallylic relationship to the oxirane ring. The cis/trans diastereoisomeric epoxide pairs 7-8 and 9-10 derived from 3- (benzyloxymethyl)cyclopentene and methyl 2-cyclopenten-1-carboxylate, respectively, were prepared and some of their opening reactions were studied. The regioselectivity observed turned out to depend on the opening reaction protocol (standard or metal-assisted), suggesting the efficacious incursion, under the appropriate conditions, of chelate bidentate species in the opening process.
