Check Digit Verification of cas no

The CAS Registry Mumber 1276121-44-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,1,2 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1276121-44:
(9*1)+(8*2)+(7*7)+(6*6)+(5*1)+(4*2)+(3*1)+(2*4)+(1*4)=138
138 % 10 = 8
So 1276121-44-8 is a valid CAS Registry Number.

Page/Page column 21, (2012/07/27)

The embodiments provide Compound KC-7, N-1-[(S)-2-(oxycodone-6-enol-carbonyl-methyl-amino)-2-carbonyl-sarcosine-ethyl amine]-arginine-glycine-acetate, or acceptable salts, solvates, and hydrates thereof. The present disclosure also provides compositions, and their methods of use, where the compositions comprise a prodrug, Compound KC-7, that provides controlled release of oxycodone. Such compositions can optionally provide a trypsin inhibitor that interacts with the enzyme that mediates the controlled release of oxycodone from the prodrug so as to attenuate enzymatic cleavage of the prodrug.

COMPOSITIONS COMPRISING ENZYME-CLEAVABLE OPIOID PRODRUGS AND INHIBITORS THEREOF
