Check Digit Verification of cas no
The CAS Registry Mumber 519138-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,9,1,3 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 519138-47:
(8*5)+(7*1)+(6*9)+(5*1)+(4*3)+(3*8)+(2*4)+(1*7)=157
157 % 10 = 7
So 519138-47-7 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.
