Check Digit Verification of cas no

The CAS Registry Mumber 27686-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,8 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27686-48:
(7*2)+(6*7)+(5*6)+(4*8)+(3*6)+(2*4)+(1*8)=152
152 % 10 = 2
So 27686-48-2 is a valid CAS Registry Number.

Tritiated Peptides. Part 9. Synthesis of 12>- and 20>-Human Calcitonin

Brundish, Derek E.,Wade, Roy

, p. 318 - 321 (1981)

The syntheses are described of human calcitonin dotriacontapeptides separately labelled with tritium in the tyrosine and histidine residues at positions 12 and 20 to specific radioactivities of 50.5 and 8.2 Ci mmol-1, respectively, by reductive de-iodination of suitable 11-32 fragments followed by rapid coupling to the 1-10 fragment and column-chromatographic purification of the reaction mixtures, using gel-filtration, and ion-exchange and high-pressure liquid chromatographic techniques.It was demonstrated that the peptide containing a disulphide bridge poisons the catalysts used for tritiation.
