133670-07-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133670-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,7 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133670-07:
(8*1)+(7*3)+(6*3)+(5*6)+(4*7)+(3*0)+(2*0)+(1*7)=112
112 % 10 = 2
So 133670-07-2 is a valid CAS Registry Number.

SYNTHESIS OF ASYMMETRIC POLYFLUORO-DIACETYLENE MONOMERS
Zhang, Yadong,Wen, Jianxun
, p. 229 - 243 (2007/10/02)
Asymmetric diacetylene monomers with polyfluoro-aromatic rings for nonlinear optics were prepared by the cross coupling of 1-bromo-acetylenes with polyfluoro-aromatic acetylenes which were prepared by nucleophilic substitution on pentafluorophenyltrimethylsilylacetylene.
