769973-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 769973-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,9,9,7 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 769973-17:
(8*7)+(7*6)+(6*9)+(5*9)+(4*7)+(3*3)+(2*1)+(1*7)=243
243 % 10 = 3
So 769973-17-3 is a valid CAS Registry Number.

Synthesis of L-6-chloropyrroloindoline of chloptosin cyclohexapeptide
Kim, Young-Ah,Han, So-Yeop
, p. 2931 - 2943 (2007/10/03)
Chloptosin is an apoptosis-inducing dimeric cyclohexapeptide. Enantio-selective synthesis of L-6-chloropyrroloindoline, as the key chiral synthon of the cyclohexapeptide of chloptosin, was successfully achieved starting from 3-chloroaniline by utilizing F
