Check Digit Verification of cas no

The CAS Registry Mumber 844644-78-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,6,4 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 844644-78:
(8*8)+(7*4)+(6*4)+(5*6)+(4*4)+(3*4)+(2*7)+(1*8)=196
196 % 10 = 6
So 844644-78-6 is a valid CAS Registry Number.

Synthesis of acyclic tetrakis- and pentakis(N2O2) ligands for single-helical heterometallic complexes with a greater number of winding turns

Akine, Shigehisa,Matsumoto, Takashi,Sairenji, Shiho,Nabeshima, Tatsuya

experimental part, p. 106 - 112 (2011/12/21)

Acyclic oligooxime ligands (H8L4 and H10L5) that have four or five N2O2 coordinating moieties (salamo moieties) were synthesised in order to obtain single-helical metal complexes with a greater number of winding turns. When the complexation of the tetraki
