76969-89-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76969-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,6 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76969-89:
(7*7)+(6*6)+(5*9)+(4*6)+(3*9)+(2*8)+(1*9)=206
206 % 10 = 6
So 76969-89-6 is a valid CAS Registry Number.

L-CYSTATHIONINE DERIVATIVES FOR THE SYNTHESIS OF PEPTIDES
Prochazka, Zdenko,Jost, Karel
, p. 1982 - 1990 (2007/10/02)
The preparation is described of L-cystathionine derivatives with amino protecting groups, which can readily be cleaved acidolytically and permit a selective acylation of both amino groups, and of a derivative with carboxyls protected by different groups.
