Check Digit Verification of cas no

The CAS Registry Mumber 871667-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,6,6 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 871667-92:
(8*8)+(7*7)+(6*1)+(5*6)+(4*6)+(3*7)+(2*9)+(1*2)=214
214 % 10 = 4
So 871667-92-4 is a valid CAS Registry Number.

Template-directed DNA photoligation via α-5-cyanovinyldeoxyuridine

Ogino, Masayuki,Yoshimura, Yoshinaga,Nakazawa, Akio,Saito, Isao,Fujimoto, Kenzo

, p. 2853 - 2856 (2005)

(Chemical Equation Presented) We describe an efficient template-directed photoligation of oligodeoxynucleotides (ODNs) using α-5- cyanovinyldeoxyuridine (αcU). An efficient photoligation was produced by photoirradiation of an ODN containing thymine at the 5′ end with an ODN containing thymine at the 5′ end in the presence of a template ODN. This photoligation method is a new and efficient way to synthesize branched ODNs.

, (2008/06/13)

An ophthalmic solution is provided for treatment of "dry eye", providing lubricating and cushioning effects for traumatized eyes, including trauma caused by the wearing of hard or gel-type contact lenses, and as a carrier for ophthalmic medicaments. The solution is an aqueous solution of polyethylene oxide, optionally polyethylene glycol, and other optional ingredients.
