Check Digit Verification of cas no

The CAS Registry Mumber 213688-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,6,8 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213688-99:
(8*2)+(7*1)+(6*3)+(5*6)+(4*8)+(3*8)+(2*9)+(1*9)=154
154 % 10 = 4
So 213688-99-4 is a valid CAS Registry Number.

Syntheses of potent LEU-enkephalin analogs possessing β-hydroxy-α,α- disubstituted-α-amino acid and their characterization to opioid receptors

Horikawa, Manabu,Shigeri, Yasushi,Yumoto, Noboru,Yoshikawa, Susumu,Nakajima, Terumi,Ohfune, Yasufumi

, p. 2027 - 2032 (2007/10/03)

Novel Leu-enkephalin (Leu-Enk) (1) analogs possessing various types of α-substituted serine instead of its glycine residue in the position 2 were synthesized via an efficient O,N-migration method. The binding characteristics of the synthetic analogs using Chinese hamster ovary (CHO) cells expressed cloned rat μ-, δ-, and κ-receptors revealed that [(1R,2S)- Ahh2]Enk (7) was the most potent agonist of δ-opioid receptors among all the synthetic analogs tested, and was 10 times more potent than the native Leu-Enk.
