Check Digit Verification of cas no

The CAS Registry Mumber 1444841-97-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,4,8,4 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1444841-97:
(9*1)+(8*4)+(7*4)+(6*4)+(5*8)+(4*4)+(3*1)+(2*9)+(1*7)=177
177 % 10 = 7
So 1444841-97-7 is a valid CAS Registry Number.

Superazaporphyrins: Meso-pentaazapentaphyrins and one of their low-symmetry derivatives

Furuyama, Taniyuki,Ogura, Yosuke,Yoza, Kenji,Kobayashi, Nagao

supporting information, p. 11110 - 11114 (2013/01/15)

Supersized: Three pentaazapentaphyrin derivatives, that is, the superazaporphyrins (SAzPs), as well as a superphthalocyanine (SPc) and a mixed low-symmetry derivative have been prepared and characterized. Decaaryl SAzPs have a distorted (4n+2) πstructure and show the Q bands at about=840-880 nm. These compounds are relatively air stable. Copyright
