Check Digit Verification of cas no
The CAS Registry Mumber 4216-02-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4216-02:
(6*4)+(5*2)+(4*1)+(3*6)+(2*0)+(1*2)=58
58 % 10 = 8
So 4216-02-8 is a valid CAS Registry Number.

Synthesis of tetraalkyl naphthalene bisanhydride and its model condensations with amines
Xiong, Kai,Xiao, Yi
supporting information, p. 3171 - 3175 (2013/06/27)
To improve the solubility of naphthalene bisanhydride (NTCA), four alkyl groups are incorporated to the naphthalene core via a five-step procedure. The new naphthalene bisanhydride derivative (TO-NTCA) shows much higher reactivity than the parent NTCA in the model condensations with ortho-diaminobenzene and 2-ethylhexylamine and gives corresponding soluble molecules with excellent yields. Hence, TO-NTCA is a potential monomer for condensations.
