Check Digit Verification of cas no

The CAS Registry Mumber 54952-08-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,5 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54952-08:
(7*5)+(6*4)+(5*9)+(4*5)+(3*2)+(2*0)+(1*8)=138
138 % 10 = 8
So 54952-08-8 is a valid CAS Registry Number.

Synthesis of analogues of ochratoxin A

Plastina, Pierluigi,Fazio, Alessia,Attya, Mohamed,Sindona, Giovanni,Gabriele, Bartolo

, p. 1799 - 1805 (2020/03/18)

Four analogues of ochratoxin A (OTA) differing for the aminoacidic moiety were synthesised using ochratoxin (OTα) as the starting material. The condensation reaction between protected amino acids and OT, carried out in the presence of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC?HCl) and N-hydroxybenzotriazole (HOBt) as coupling agents, followed by deprotection and PTLC purification afforded OTA alanine, leucine, serine and tryptophane analogues in satisfactory yields (33-47%, based on OT).
