Check Digit Verification of cas no

The CAS Registry Mumber 84817-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,1 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84817-47:
(7*8)+(6*4)+(5*8)+(4*1)+(3*7)+(2*4)+(1*7)=160
160 % 10 = 0
So 84817-47-0 is a valid CAS Registry Number.

A short and flexible route to tetrahydropyran-4-ones via conjugated nitrile oxides cycloaddition and oxa-Michael cyclization: A concise diastereoselective total synthesis of (±)-diospongin A

Yao, Hongliang,Ren, Jingyun,Tong, Rongbiao

supporting information, p. 193 - 195 (2013/02/23)

A short and flexible [3+2+1] synthetic strategy was developed for the synthesis of substituted tetrahydropyran-4-ones, featuring [3+2]-cycloaddition of α,β-unsaturated nitrile oxides and alkenes and oxa-Michael cyclization in a 6-endo-trig fashion. The efficiency of this synthetic strategy was further demonstrated by the concise total synthesis of (±)-diospongin A in 8 steps with 20.2% yield. This journal is The Royal Society of Chemistry.
