Check Digit Verification of cas no

The CAS Registry Mumber 172101-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,1,0 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 172101-94:
(8*1)+(7*7)+(6*2)+(5*1)+(4*0)+(3*1)+(2*9)+(1*4)=99
99 % 10 = 9
So 172101-94-9 is a valid CAS Registry Number.

A unified strategy for the total synthesis of the angucycline antibiotics SF 2315A, urdamycinone B, and the shunt metabolite 104-2

Kim, Kyungjin,Boyd, Vincent A.,Sobti, Aditya,Sulikowski, Gary A.

, p. 3 - 22 (2007/10/03)

Total syntheses of the angucycline antibiotics SF 2315A (2), urdamycinone B (4), and the shunt metabolite 104-2 (5) are described, as well as an approach toward the synthesis of SF 2315B (3). All four syntheses feature a Diels-Alder cycloaddition between a bromojuglone derivative and an optically active diene (25a), the latter derived from (-)-quinic acid. Subsequent key transformations include (i) stereocontrolled introduction of ring fusion oxygen functionality featured in SF 2315A (2) and SF 2315 B (3), (ii) preparation of C-glycosyl juglone 53, and (iii) NMO mediated oxidative aromatization of 60.
