The chemical process described involves the conversion of S-benzyl-N-(toluene-4-sulfonyl)-cysteinyl to tyrosyl, and then to phenylalanine methyl ester. S-benzyl-N-(toluene-4-sulfonyl)-cysteinyl is a protected form of cysteine, where the thiol group is blocked by a benzyl group and the amino group is protected by a tosyl group. The first step in this process is the deprotection of the cysteine, which involves removing the benzyl and tosyl groups to expose the thiol and amino groups. This deprotected cysteine can then undergo a reaction to form a tyrosyl group, which involves the oxidation of the thiol group to a sulfonic acid and the subsequent loss of a hydrogen sulfide molecule. The final step in this process is the conversion of the tyrosyl group to phenylalanine methyl ester, which involves the removal of the hydroxyl group from the tyrosine and the addition of a methyl ester group. This entire process is a complex series of chemical reactions that require specific conditions and reagents to proceed efficiently.

2362-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2362-43-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,6 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 2362-43:
(6*2)+(5*3)+(4*6)+(3*2)+(2*4)+(1*3)=68
68 % 10 = 8
So 2362-43-8 is a valid CAS Registry Number.
