207281-70-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 207281-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,2,8 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 207281-70:
(8*2)+(7*0)+(6*7)+(5*2)+(4*8)+(3*1)+(2*7)+(1*0)=117
117 % 10 = 7
So 207281-70-7 is a valid CAS Registry Number.

Radical reactions leading to substituted pyroglutamates
Baker, S. Richard,Parsons, Andrew F.,Wilson, Michelle
, p. 2815 - 2818 (2007/10/03)
The Bu3SnH mediated cyclisation of a serine-derived dehydroalanine was shown to provide an efficient approach to a protected 4-phenylpyroglutamate which was elaborated to 4-phenylglutamic acid in good yield. Cyclisation reactions of this type w
