Check Digit Verification of cas no
The CAS Registry Mumber 189099-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,9 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189099-56:
(8*1)+(7*8)+(6*9)+(5*0)+(4*9)+(3*9)+(2*5)+(1*6)=197
197 % 10 = 7
So 189099-56-7 is a valid CAS Registry Number.

, p. 429 - 433 (2007/10/03)
A variety of disubstituted diphenylacetylenes and related compounds have been synthesized by a modified Horner-Emmons reaction, and their second harmonic generation (SHG) has been evaluated by the Kurtz powder method. The diphenylacetylenes with weak electron-donating and -withdrawing groups are found to be efficient for SHG, as well as having the lowest cut-off wavelength.
