Check Digit Verification of cas no

The CAS Registry Mumber 1415726-82-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,5,7,2 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1415726-82:
(9*1)+(8*4)+(7*1)+(6*5)+(5*7)+(4*2)+(3*6)+(2*8)+(1*2)=157
157 % 10 = 7
So 1415726-82-7 is a valid CAS Registry Number.

Organocatalyzed enantioselective decarboxylative stereoablation reaction for the construction of 3,3′-disubstituted oxindoles using β-ketoacids and 3-halooxindoles

Zuo, Jian,Liao, Yu-Hua,Zhang, Xiao-Mei,Yuan, Wei-Cheng

, p. 11325 - 11332 (2013/02/23)

An unprecedented method for the construction of optically active 3,3′-disubstituted oxindoles via an organocatalyzed decarboxylative stereoablation reaction has been developed. We describe the first asymmetric reaction between β-ketoacids and 3-halooxindoles utilizing an organocatalyst. This method allows for the formation of a variety of 3,3′-disubstituted oxindoles bearing a keto-carbonyl group, which are not easily accessible using other methodologies, in moderate to good yields with high enantioselectivities.
