Check Digit Verification of cas no
The CAS Registry Mumber 84987-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,8 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84987-89:
(7*8)+(6*4)+(5*9)+(4*8)+(3*7)+(2*8)+(1*9)=203
203 % 10 = 3
So 84987-89-3 is a valid CAS Registry Number.

Δ1,9-Octal-2-ones with angular substituents R have been synthesized and subjected to reduction conditions by employing the ethylenediamine complex of CrSO4 in aqueous DMF at 25 deg C.For R = Me, CH2OCH2OCH2CH2OMe, CH2OTHP, and COOMe negligible reduction was observed within 60 h, and starting materials were recovered in 60 percent yields.For R= CH2OH and COOH complete disappearance of starting material was achieved in 30-64 h, with isolation of ca. 40 percent of saturated ketone having exclusively cis stereochemistry.These results are interpreted in terms of precoordination of Cr(II) to the hydroxyl function, internal donation to yield a chelated organochromium intermediate, and stereoretentive hydrolysis to cis product.
