Check Digit Verification of cas no

The CAS Registry Mumber 172170-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,1,7 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172170-18:
(8*1)+(7*7)+(6*2)+(5*1)+(4*7)+(3*0)+(2*1)+(1*8)=112
112 % 10 = 2
So 172170-18-2 is a valid CAS Registry Number.

Formal total synthesis of nikkomycin B based on a lipase-catalysed hydrolysis of an acetate possessing two stereogenic centers

Akita, Hiroyuki,Chen, Cheng Yu,Kato, Keisuke

, p. 11011 - 11026 (2007/10/03)

A stereoselective synthesis of the versatile chiral synthon possessing two stereogenic centers, (2S,3S)-11 (>99% ee) was achieved by using chemo- enzymatic method. The conversion of (2S,3s)-11 into the homochiral intermediates (2S,3S,4S)-25 and (2S,3S,4S)-27 corresponding to the N-terminal amino acid moiety of nikkomycin B(1) and their application to the formal total synthesis of nikkomycin B(1) are described.

A formal total synthesis of nikkomycin B based on enzymatic resolution of a primary alcohol possessing two stereogenic centers
