16460-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16460-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,6 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16460-74:
(7*1)+(6*6)+(5*4)+(4*6)+(3*0)+(2*7)+(1*4)=105
105 % 10 = 5
So 16460-74-5 is a valid CAS Registry Number.

HIGHLY STEREOSELECTIVE PHOTODIMERIZATION OF 1,3-DIMETHYLTHYMINE IN LIQUID CRYSTALLINE MEDIA

Kunieda, Takehisa,Takahashi, Toshie,Hirobe, Masaaki

, p. 5107 - 5108 (1983)

Ordered media such as cholesteric and smectic solvents greatly enhance the stereoselectivity and the rate in photodimerization of 1,3-dimethylthymine, in contrast to the isotropic phase reactions leading to a poor product-selectivity.
