Check Digit Verification of cas no

The CAS Registry Mumber 133992-79-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,9 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133992-79:
(8*1)+(7*3)+(6*3)+(5*9)+(4*9)+(3*2)+(2*7)+(1*9)=157
157 % 10 = 7
So 133992-79-7 is a valid CAS Registry Number.

Application of 4-alkoxy-1,1,1-trifluoro[chloro]alk-3-en-2-ones as selective protecting groups of amino acids

Zanatta, Nilo,Squizani, Adriana M. C.,Fantinel, Leonardo,Nachtigall, Fabiane M.,Bonacorso, Helio G.,Martins, Marcos A. P.

, p. 2409 - 2415 (2007/10/03)

A convenient selective protection of the α-amino carboxyl group of amino acids bearing reactive side chain groups such as arginine, asparagine, glutamine, cysteine, histidine, serine and lysine, using 4-alkoxy-1,1,1-trifluoro[chloro]alk-3-en-2-ones is reported. The reactions were performed without esterification of the carboxyl group and N-deprotection was carried out using a six molar solution of hydrochloric acid.
