Check Digit Verification of cas no

The CAS Registry Mumber 1276122-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,1,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1276122-63:
(9*1)+(8*2)+(7*7)+(6*6)+(5*1)+(4*2)+(3*2)+(2*6)+(1*3)=144
144 % 10 = 4
So 1276122-63-4 is a valid CAS Registry Number.

Transformation of anionically activated trifluoromethyl groups to heterocycles under mild aqueous conditions

Qiao, Jennifer X.,Wang, Tammy C.,Hu, Carol,Li, Jianqing,Wexler, Ruth R.,Lam, Patrick Y. S.

scheme or table, p. 1804 - 1807 (2011/06/19)

The (hetero)aromatic trifluoromethyl group is present in many biologically active molecules and is generally considered to be chemically stable. In this paper, a convenient one-step synthesis of C-C linked aryl-heterocycles or heteroaryl-heterocycles in good to excellent yields via the reaction of anionically activated trifluoromethyl groups with amino nucleophiles containing a second NH, OH, or SH nucleophile in 1 N sodium hydroxide is reported. The method has high functional group tolerability and is potentially useful in parallel synthesis.
