111102-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111102-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,0 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111102-73:
(8*1)+(7*1)+(6*1)+(5*1)+(4*0)+(3*2)+(2*7)+(1*3)=49
49 % 10 = 9
So 111102-73-9 is a valid CAS Registry Number.

Regiospecific Synthesis of 3-Substituted L-Histidines
Hodges, John C.
, p. 20 - 24 (2007/10/02)
3-Substituted L-histidine derivatives were prepared by a regiospecific alkylation of N,1-bis-Boc-L-histidine methyl ester with in situ-generated alkyl triflates, benzyl triflates, and benzyl mesylates.Subsequent acid hydrolysis of N-Boc and methyl ester p
