Check Digit Verification of cas no
The CAS Registry Mumber 126330-78-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,3 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126330-78:
(8*1)+(7*2)+(6*6)+(5*3)+(4*3)+(3*0)+(2*7)+(1*8)=107
107 % 10 = 7
So 126330-78-7 is a valid CAS Registry Number.

QUANTITATIVE SYNTHESIS OF L OR D N2-TERTBUTOXYCARBONYL-2,3-DIAMINOPROPANOIC ACID FROM PROTECTED L OR D SERINE-β-LACTONE
Kucharczyk, N.,Badet, B.,Goffic, F. Le
, p. 1603 - 1610 (2007/10/02)
The reaction of ammonia on protected L or D serine-β-lactone was reinvestigated.An easy synthesis of N2-tertbutoxycarbonyl-L-2,3-diaminopropanoic acid (and D enantiomer), an important precursor of several antibiotics is proposed.
