99909-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99909-57-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,0 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99909-57:
(7*9)+(6*9)+(5*9)+(4*0)+(3*9)+(2*5)+(1*7)=206
206 % 10 = 6
So 99909-57-6 is a valid CAS Registry Number.

, p. 1656 - 1661 (2007/10/02)
In order to study the structure-activity relationships of natural opioid deltorphins (H-Tyr-D-Met-Phe-His-Leu-Met-Asp-NH2 and H-Tyr-D-Ala-Phe-Asp[or Glu]-Val-Val-Gly-NH2), 15 analogues were synthesized by the solution method. Their a
