Check Digit Verification of cas no

The CAS Registry Mumber 1221689-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,6,8 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1221689-41:
(9*1)+(8*2)+(7*2)+(6*1)+(5*6)+(4*8)+(3*9)+(2*4)+(1*1)=143
143 % 10 = 3
So 1221689-41-3 is a valid CAS Registry Number.

Figure Presented Stolen identity: The molecular geometries of a series of cross-linkers that bear between one and four pyridyl moieties are expressed in the optical properties of AuNP assemblies (see picture). TEM analysis indicates that the molecular-level structural differences of the cross-linkers are also transferred at the submicrometer level in the formation of the AuNP assemblies.
