Check Digit Verification of cas no

The CAS Registry Mumber 1453863-35-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,8,6 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1453863-35:
(9*1)+(8*4)+(7*5)+(6*3)+(5*8)+(4*6)+(3*3)+(2*3)+(1*5)=178
178 % 10 = 8
So 1453863-35-8 is a valid CAS Registry Number.

The quinine thiourea-catalyzed asymmetric Strecker reaction: An approach for the synthesis of 3-aminooxindoles

Wang, Dong,Liang, Jinyan,Feng, Jingchao,Wang, Kairong,Sun, Quantao,Zhao, Long,Li, Dan,Yan, Wenjin,Wang, Rui

, p. 548 - 558 (2013)

An organocatalytic enantioselective Strecker reaction for the synthesis of 3-amino-3-cyanooxindoles has been developed. Employing a quinine-derived thiourea catalyst, the nucleophilic addition of trimethylsilyl cyanide to N-Boc-ketimines affords 3-amino-3-canooxindoles in good to excellent yields (78-98%) and very good enantioselectivities (up to 94%). Furthermore, to the best of our knowledge, this method also represents the first enantioselective organocatalyzed Strecker reaction with N-Boc-ketimines as electrophiles.
