Check Digit Verification of cas no

The CAS Registry Mumber 227005-70-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,0,0 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 227005-70:
(8*2)+(7*2)+(6*7)+(5*0)+(4*0)+(3*5)+(2*7)+(1*0)=101
101 % 10 = 1
So 227005-70-1 is a valid CAS Registry Number.

Enantioselective synthesis of functionalized α-amino acids via a chiral guanidine catalyzed Michael addition reaction

Ma, Dawei,Cheng, Kejun

, p. 713 - 719 (1999)

Several chiral guanidines were evaluated as catalysts for the Michael reaction of glycine derivatives 7 with acrylic esters 8. The best result (30.4% ee) was obtained when 7b was reacted with 8b under the catalysis of guanidine 1 in THF.
