110881-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110881-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,8,8 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110881-59:
(8*1)+(7*1)+(6*0)+(5*8)+(4*8)+(3*1)+(2*5)+(1*9)=109
109 % 10 = 9
So 110881-59-9 is a valid CAS Registry Number.

N,N-DIALLYL-.

Synthesis of bis left bracket N,N-diallyl- left bracket D-Ala**2, L-Leu**5 right bracket -enkephalyl right bracket cystine, which is expected to be a selective opioid delta -receptor antagonist, was studied. The mercapto group of cysteine was protected by the dimethylphosphinothioyl(Mpt) group. For the removal of this group without damaging the allyl moiety, new mild removal conditions by use of KF/18-crown-6 in a solvent mixture of acetonitrile-methanol are proposed. Bis left bracket D-Ala**2, L-Leu**5 right bracket -enkephalyl right bracket cystine was also prepared in a similar manner.
