Check Digit Verification of cas no

The CAS Registry Mumber 219657-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219657-90:
(8*2)+(7*1)+(6*9)+(5*6)+(4*5)+(3*7)+(2*9)+(1*0)=166
166 % 10 = 6
So 219657-90-6 is a valid CAS Registry Number.

Synthesis of imidazo[2,1-b][2H-1,3,4]thiadiazines and 1,2,4-triazolo[3,4-b][2H-1,3,4]thiadiazines

Knak, Stefanie,Pfeiffer, Wolf-Diethard,Dollinger, Horst,Saghyan, Ashot S.,Langer, Peter

, p. 463 - 467 (2015/03/30)

Imidazo[2,1-b][2H-1,3,4]thiadiazines were prepared by cyclization of 2-amino-5-(4-chlorophenyl)-6H-1,3,4-thiadiazine with α-haloketones. 1,2,4-Triazolo[3,4-b][2H-1,3,4]thiadiazines were prepared by cyclization of 4-amino-5-sulfanyl-l,2,4-triazoles with ph

Structure-based design and synthesis of potent matrix metalloproteinase inhibitors derived from a 6H-1,3,4-thiadiazine scaffold

Schr?der,Henke,Wenzel,Brandstetter,Stammler,Stammler,Pfeiffer,Tschesche

, p. 3231 - 3243 (2007/10/03)

We describe a new generation of heterocyclic nonpeptide matrix metalloproteinase (MMP) inhibitors derived from a 6H-1,3,4-thiadiazine scaffold. A screening effort was utilized to identify some chiral 6-methyl-1,3,4-thiadiazines that are weak inhibitors of
