Check Digit Verification of cas no

The CAS Registry Mumber 119221-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,2 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119221-25:
(8*1)+(7*1)+(6*9)+(5*2)+(4*2)+(3*1)+(2*2)+(1*5)=99
99 % 10 = 9
So 119221-25-9 is a valid CAS Registry Number.

Peptides Related to Leucine-/Methionine-enkephalinamides: Synthesis and Biological Activities

Sivanandaiah, K. M.,Gurusiddappa, S.,Babu, V. V. Suresh

, p. 645 - 648 (2007/10/02)

Six analogues of leucine-/methionine-enkephalinamides have been synthesised by substitution of D-amino acids at position-2 and Nle or Eth at position-5 by solid phase technique employing mainly the base labile 9-fluorenyl-methyloxycarbonyl group for Nα-protection.One of the analogues, tyrosyl-D-norvalyl-glycyl-phenylalanyl-ethioninamide is found to be 21.6 times more potent than morphine in the guinea pig ileum assay.
