Check Digit Verification of cas no

The CAS Registry Mumber 74741-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,4 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74741-34:
(7*7)+(6*4)+(5*7)+(4*4)+(3*1)+(2*3)+(1*4)=137
137 % 10 = 7
So 74741-34-7 is a valid CAS Registry Number.

Benzodioxans by Oxidative Phenol Coupling. Synthesis of Silybin

Merlini, Lucio,Zanarotti, Antonio,Pelter, Andrew,Rochefort, Malcolm P.,Haensel, Rudolf

, p. 775 - 778 (2007/10/02)

Oxidative coupling of substituted catechols with isoeugenol or coniferyl alcohol in the presence of silver oxide affords 2,3-trans-1,4-benzodioxans in good yield.The reaction is highly regioselective when the catechol bears an alkyl substituent, much less
