Check Digit Verification of cas no

The CAS Registry Mumber 1588428-28-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,8,4,2 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1588428-28:
(9*1)+(8*5)+(7*8)+(6*8)+(5*4)+(4*2)+(3*8)+(2*2)+(1*8)=217
217 % 10 = 7
So 1588428-28-7 is a valid CAS Registry Number.

In situ generation of electrophilic trifluoromethylthio reagents for enantioselective trifluoromethylthiolation of oxindoles

Zhu, Xing-Li,Xu, Jin-Hui,Cheng, Dao-Juan,Zhao, Li-Jiao,Liu, Xin-Yuan,Tan, Bin

, p. 2192 - 2195 (2014/05/06)

An organocatalytic asymmetric trifluoromethylthiolation reaction via in situ generation of active electrophilic trifluoromethylthio species involving trichloroisocyanuric acid and AgSCF3 as a practical and easily handled electrophilic SCF3 source for CSP 3-SCF3 bond formation was developed. Reactions with this one-pot version strategy occurred in good yields and excellent stereoselectivities to access enantiopure oxindoles bearing a SCF 3-substituted quaternary chiral center. The straightforward process described here makes use of simple starting materials and proceeds under mild conditions, which will be useful in medicinal chemistry and diversity-oriented syntheses.
