Check Digit Verification of cas no
The CAS Registry Mumber 178100-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,1,0 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 178100-18:
(8*1)+(7*7)+(6*8)+(5*1)+(4*0)+(3*0)+(2*1)+(1*8)=120
120 % 10 = 0
So 178100-18-0 is a valid CAS Registry Number.

A radical cyclisation approach to pyroglutamates
Goodall, Karen,Parsons, Andrew F.
, p. 6739 - 6758 (2007/10/03)
Treatment of serine-derived N-(α-haloacetamido)dehydroalanine derivatives with tributyltin hydride in boiling benzene or toluene afforded pyroglutamates in 47-84% yield. The radical cyclisation reaction, which proceeded regioselectively in a disfavoured 5
