Check Digit Verification of cas no
The CAS Registry Mumber 155831-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,3 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 155831-46:
(8*1)+(7*5)+(6*5)+(5*8)+(4*3)+(3*1)+(2*4)+(1*6)=142
142 % 10 = 2
So 155831-46-2 is a valid CAS Registry Number.

Novel intermolecular and intramolecular generations of ortho-quinone methides and their formal [4+2]-cycloaddition reactions with olefins catalyzed by PtCl4 and AuCl3 under mild conditions have been developed. Good to excellent yields (up to 99%) and diastereoselectivity (up to >99:1) of the chromans were obtained. PtCl4 was found to be effective and compatible with various functional groups present in the substrates. A mechanism accounting for its catalytic cycle is proposed and discussed.
