1173659-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173659-19-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,6,5 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1173659-19:
(9*1)+(8*1)+(7*7)+(6*3)+(5*6)+(4*5)+(3*9)+(2*1)+(1*9)=172
172 % 10 = 2
So 1173659-19-2 is a valid CAS Registry Number.

experimental part, p. 121 - 127 (2010/04/05)
The present investigation deals with the synthesis of a N-methylated cyclotetrapeptide, hirsutide (2), by coupling of the dipeptide units Boc-l-phenylalanyl-l-N-methylphenylalanine-OH and l-valyl-l-N- methylphenylalanine-OMe followed by cyclization of the
