Check Digit Verification of cas no

The CAS Registry Mumber 841244-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,1,2,4 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 841244-97:
(8*8)+(7*4)+(6*1)+(5*2)+(4*4)+(3*4)+(2*9)+(1*7)=161
161 % 10 = 1
So 841244-97-1 is a valid CAS Registry Number.

Preparation and properties of 1,2-bis[(2,4,6-tri-t-butylphenyl) phosphinidene]cyclobuta[l]phenanthrene

Nakamura, Akitake,Kawasaki, Subaru,Toyota, Kozo,Yoshifuji, Masaaki

, p. 1570 - 1571 (2004)

Sterically protected 1,2-bis[(2,4,6-tri-t-butylphenyl)phosphinidene] cyclobuta[l]phenanthrene (4) and its group(6) and group(10) transition metal complexes were prepared. X-ray crystallographic analysis of 4 revealed a planar structure of the diphosphinidenecyclobuta[l]phenanthrene moiety. Copyright
