Check Digit Verification of cas no
The CAS Registry Mumber 158322-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,3,2 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158322-09:
(8*1)+(7*5)+(6*8)+(5*3)+(4*2)+(3*2)+(2*0)+(1*9)=129
129 % 10 = 9
So 158322-09-9 is a valid CAS Registry Number.

A concise synthesis of (E)- and (Z)-neomanoalides
Jefford,Rossier,Boukouvalas,Huang
, p. 661 - 667 (1994)
The first synthesis of (Z)-neomanoalide (4) and an improved synthesis of its (E)-isomer 3 was accomplished in a concise, regiocontrolled manner by exploiting 2-[(tert-butyl)dimethylsiloxy]-4{[(tert-butyl)dimethylsiloxy]methyl} furan (6) as the key reagent
