74083-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74083-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,8 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74083-89:
(7*7)+(6*4)+(5*0)+(4*8)+(3*3)+(2*8)+(1*9)=139
139 % 10 = 9
So 74083-89-9 is a valid CAS Registry Number.

Synthesis of porcine motilin via its sulfoxides
Izeboud, E.,Beyerman, H. C.
, p. 124 - 130 (2007/10/02)
The protected segments corresponding to sequences 1-8 and 9-22 proposed for porcine motilin were synthesized mainly by the repetitive excess mixed anhydride (REMA) method.Mixed anhydride coupling of the segments gave protected motilin sulfoxide (Scheme).D
