Check Digit Verification of cas no
The CAS Registry Mumber 128227-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,2 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128227-40:
(8*1)+(7*2)+(6*8)+(5*2)+(4*2)+(3*7)+(2*4)+(1*0)=117
117 % 10 = 7
So 128227-40-7 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS OF 3,4-CIS-SUBSTITUTED β-LACTAMS VIA CHIRAL NOREPHEDRINE-DERIVED OXAZOLIDINES.
Cardani, S.,Gennari, C.,Scolastico, C.,Villa, R.
, p. 7397 - 7404 (2007/10/02)
A diastereo- and enantioselective approach to functionalized 3,4-cis-β-lactams 9 and 16 was developed based on the use of chiral norephedrine-derived oxazolidines.The key-steps in the synthesis of 9 (Scheme 1) are the potassium hypochlorite epoxidation of
