Check Digit Verification of cas no

The CAS Registry Mumber 94819-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,1 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94819-70:
(7*9)+(6*4)+(5*8)+(4*1)+(3*9)+(2*7)+(1*0)=172
172 % 10 = 2
So 94819-70-2 is a valid CAS Registry Number.

, p. 37 - 42 (2007/10/02)

cis- and trans-4,5-Tetramethylene-4,5-dihydro-6H-1,3-thiazines (2) were synthesized by heating the corresponding oxazines (1) with phosphorus pentasulfide.In the case of the 5,6-polymethylene analogues, trans-1,3-thiazines (4) were obtained from cis-1,3-o

Stereostructure of Condendsed-Skeleton cis- and trans-Dihydro-1,3-thiazines and 1-Thia-3-azaspiroalkenes

Sohar, P.,Simon, L.,Bernath, G.

, p. 597 - 602 (2007/10/02)

The stereostructures of some condensed-skeleton cis- and trans-dihydro-1,3-thiazines and 1-thia-2-phenyl-3-azaspiroalk-2-enes (n = 3-6) were established by 1H and 13C NMR spectroscopy.A comparative study indicated that the cis-thiazines have greater
