171016-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171016-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,0,1 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 171016-58:
(8*1)+(7*7)+(6*1)+(5*0)+(4*1)+(3*6)+(2*5)+(1*8)=103
103 % 10 = 3
So 171016-58-3 is a valid CAS Registry Number.

Synthesis of pyrrolobenzodiazepines via the PIFA oxidation of amines. Synthesis of 8-deoxy DC-81
Kraus, George A.,Melekhov, Alex
, p. 11749 - 11754 (2007/10/03)
PIFA can be used to introduce the imine moiety into a precursor to the pyrrolobenzodiazepines in 62% yield. This oxidation completes an efficient four-step synthesis of 8-deoxy DC-81.
