Check Digit Verification of cas no

The CAS Registry Mumber 157769-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,6 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157769-09:
(8*1)+(7*5)+(6*7)+(5*7)+(4*6)+(3*9)+(2*0)+(1*9)=180
180 % 10 = 0
So 157769-09-0 is a valid CAS Registry Number.

Synthesis and stability of two indomethacin prodrugs

Chandrasekaran, Shyamala,Al-Ghananeem, Abeer M.,Riggs, Robert M.,Crooks, Peter A.

, p. 1874 - 1879 (2007/10/03)

The purpose of this study was to synthesize and study the in vitro enzymatic and non-enzymatic hydrolysis of indomethacin-TEG ester and amide prodrugs. It was found that the ester conjugate 10 was comparatively stable between pH 3 and 6 (half-life >90 h),
