26987-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26987-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,8 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 26987-64:
(7*2)+(6*6)+(5*9)+(4*8)+(3*7)+(2*6)+(1*4)=164
164 % 10 = 4
So 26987-64-4 is a valid CAS Registry Number.

Affinity-Labelling Corticoids I. Synthesis of 21-Chloroprogesterone, Deoxycorticosterone 21-(1-Imidazole) Carboxylate, 21-Deoxy-21-Chloro Dexamethasone, and Dexamethasone 21-Mesylate, 21-Bromoacetate, and 21-Iodoacetate

Dunkerton, Lois V.,Markland, Francis S.,Li, Ming P.

, p. 1 - 6 (2007/10/02)

The efficient and unambiguous preparation of several C-21 substituted affinity-labelling corticoids are described.Included is an improved procedure for the preparation of 21-chloroprogesterone and the first reported synthesis of deoxycorticosterone 21-(1-imidazole) carboxylate.Dexamethasone derivatives prepared include seperate and unambiguous synthesis of 21-deoxy-21-chlorodexamethasone and dexamethasone 21-mesylate, as well as the first reported synthesis of dexamethasone 21-bromoacetate and dexamethasone 21-iodoacetate.
