Check Digit Verification of cas no

The CAS Registry Mumber 170943-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,9,4 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 170943-16:
(8*1)+(7*7)+(6*0)+(5*9)+(4*4)+(3*3)+(2*1)+(1*6)=135
135 % 10 = 5
So 170943-16-5 is a valid CAS Registry Number.

Orthogonality and compatibility between Tsc and Fmoc amino-protecting groups

Choi, Jin Seok,Kang, Hunhui,Jeong, Nakcheol,Han, Hogyu

, p. 2493 - 2503 (2005)

New deprotection conditions that provide a complete orthogonality between Tsc and Fmoc amino-protecting groups are described. The potential of these orthogonal deprotection conditions was then demonstrated by the efficient solid-phase synthesis of branched peptides 20 and 21 using doubly protected amino acids such as Tsc-Lys(Fmoc)-OH 4c and Fmoc-Lys(Tsc)-OH 4d.
