Check Digit Verification of cas no

The CAS Registry Mumber 85313-60-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,3,1 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 85313-60:
(7*8)+(6*5)+(5*3)+(4*1)+(3*3)+(2*6)+(1*0)=126
126 % 10 = 6
So 85313-60-6 is a valid CAS Registry Number.

The 1-(3,5-Di-tert-butylphenyl)-1-methylethoxycarbonyl (t-Bumeoc) Residue, a Protecting Group Cleavable under Extremely Mild Acidic Conditions

Voelter, Wolfgang,Mueller, Juergen

, p. 248 - 260 (2007/10/02)

The synthesis of 1-(3,5-di-tert-butylphenyl)-1-methylethoxycarbonyl fluoride (8) and its reaction with selected amino acids as well as the 13C NMR spectroscopic characterization of t-Bumeoc derivatives are described.The new protecting group is cleavable under very mild acidic conditions.The kinetics of the cleavage is studied by high-performance liquid chromatography (HPLC).The utility of the t-Bumeoc compared to the Adpoc protecting group is demonstrated taking a derivative of the molluscan neuropeptide as an example.
