Check Digit Verification of cas no
The CAS Registry Mumber 397301-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,7,3,0 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 397301-38:
(8*3)+(7*9)+(6*7)+(5*3)+(4*0)+(3*1)+(2*3)+(1*8)=161
161 % 10 = 1
So 397301-38-1 is a valid CAS Registry Number.

The dimeric derivative of Aripiprazole was synthesized via the two notable synthetic technologies as a key step: (1) efficient aldehyde bis-arylation by Bi(OTf)3 and (2) facile Wynberg amination at room temperature. The synthesis has established the structural identity with the minor contaminant sometimes present in Aripiprazole.
