Check Digit Verification of cas no

The CAS Registry Mumber 91640-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,4 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91640-02:
(7*9)+(6*1)+(5*6)+(4*4)+(3*0)+(2*0)+(1*2)=117
117 % 10 = 7
So 91640-02-7 is a valid CAS Registry Number.

Palladium-catalyzed regiospecific tandem allylation of 2-aminophenols using 2-butene-1,4-diol

Yang, Shyh-Chyun,Lai, Hwe-Chen,Tsai, Yan-Chiu

, p. 2693 - 2697 (2004)

The direct activation of C-O bonds in 2-butene-1,4-diol by palladium complexes has been accelerated by carrying out the reactions in the presence of a titanium reagent. Palladium-catalyzed regiospecific tandem allylation of 2-aminophenols with 2-butene-1,4-diol leads to 3,4-dihydro-2-vinyl-2H-1,4- benzoxazines.
