Check Digit Verification of cas no
The CAS Registry Mumber 108199-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,9 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 108199-25:
(8*1)+(7*0)+(6*8)+(5*1)+(4*9)+(3*9)+(2*2)+(1*5)=133
133 % 10 = 3
So 108199-25-3 is a valid CAS Registry Number.

Synthesis and crystal structures of 2,3,12,13-tetraalkoxy-21,23- dithiaporphyrins and 2,3-dialkoxy-21-monothiaporphyrins
Agarwal, Neeraj,Hung,Ravikanth, Mangalampalli
, p. 10671 - 10680 (2007/10/03)
The tetraalkoxy and dialkoxy substituted 21,23-dithiaporphyrins and 21-monothiaporphyrins, respectively, having methoxy, butoxy, octyloxy and dodecyloxy substituents at β-thiophene carbons were synthesized and characterized. The X-ray structure was solved for tetrabutoxy substituted 21,23-dithiaporphyrin and it exhibited a more planar structure compared with unsubstituted S2TPP, whereas the dimethoxy substituted 21-monothiaporphyrin showed a saddle shaped structure similar to unsubstituted STPPH. A series of 21,23-dithia and 21-monothiaporphyrins having methoxy, butoxy, octyloxy and dodecyloxy substituents at β-thiophene carbons were synthesized and characterized.
