Check Digit Verification of cas no

The CAS Registry Mumber 134452-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,5 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134452-34:
(8*1)+(7*3)+(6*4)+(5*4)+(4*5)+(3*2)+(2*3)+(1*4)=109
109 % 10 = 9
So 134452-34-9 is a valid CAS Registry Number.

An efficient preparation of optically active α-furfuryl amide by kinetic resolution using the modified Sharpless asymmetric epoxidation reagents

Zhou,Lu,Wang

, p. 2641 - 2654 (1993)

Kinetic resolution of α-furfuryl amide was first carried out by using the modified Sharpless asymmetric epoxidation reagent to give the slow-reacting enantiomers, (S)-1(a-h) and (R)-1(b,f) in high enantioselectivity (90-100% e.e) and high chemical yield (
