Check Digit Verification of cas no
The CAS Registry Mumber 203783-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,8 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 203783-46:
(8*2)+(7*0)+(6*3)+(5*7)+(4*8)+(3*3)+(2*4)+(1*6)=124
124 % 10 = 4
So 203783-46-4 is a valid CAS Registry Number.

Towards the semi-synthesis of didemnin M. solution and solid phase synthesis of the pseudotetrapeptide: pGlu-Glnψ[COO]Ala-Pro-OH
Wen, James J.,Crews, Craig M.
, p. 779 - 782 (2007/10/03)
Two approaches, solution and solid phase syntheses, were developed for the synthesis of the pseudotetrapeptide, pGlu-Glnψ[COO]Ala-Pro-OH. Both approaches gave comparable synthetic yields, but the latter approach provided an expedient entry to the synthesis of the target compound with higher product purity.
