482-49-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 482-49-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 482-49:
(5*4)+(4*8)+(3*2)+(2*4)+(1*9)=75
75 % 10 = 5
So 482-49-5 is a valid CAS Registry Number.

Crystal structure of doisynolic acid and the structure of other products formed during its synthesis

Chi, Dae Yoon,Wilson, Scott R.,Katzenellenbogen, John A.

, p. 261 - 264 (1995)

The crystal structure of the D-seco-estrogen doisynolic acid shows it to have the natural S configuration at the position derived from C-14 in estrone.Two major by-products during the synthesis of doisynolic acid from estrone are shown to be dimeric steroids.One is an aldol condensation product, and the other appears to arise from an alkaline cleavage of the aldol product. - Keywords: doisynolic acid; estrogens; X-ray crystallography; stereochemistry
