157401-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157401-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,0 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157401-05:
(8*1)+(7*5)+(6*7)+(5*4)+(4*0)+(3*1)+(2*0)+(1*5)=113
113 % 10 = 3
So 157401-05-3 is a valid CAS Registry Number.

Synthesis of deoxy analogs of HEPT involving a palladium (0) catalyzed coupling
Pontikis, Renee,Monneret, Claude
, p. 4351 - 4354 (1994)
Deoxy analogs of HEPT (4-7) were prepared by Pd(0) catalyzed coupling between 6-(phenylthio)thymine and cinnamyl acetate or 3-(heteroaryl) allyl acetates.
