Check Digit Verification of cas no

The CAS Registry Mumber 157953-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,5 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157953-26:
(8*1)+(7*5)+(6*7)+(5*9)+(4*5)+(3*3)+(2*2)+(1*6)=169
169 % 10 = 9
So 157953-26-9 is a valid CAS Registry Number.

REGIOSELECTIVE PRENYLATION OF PHENOLS BY PALLADIUM CATALYST: SYNTHESES OF PRENYLPHENOLS AND CHROMANS

Tsukayama, Masao,Kikuchi, Makoto,Kawamura, Yasuhiko

, p. 1487 - 1490 (2007/10/02)

The palladium-catalyzed coupling reaction of iodophenols (1) with 2-methyl-3-butyn-2-ol gave alkynylphenols (2).Catalytic hydrogenation of 2 over Raney nickel and the subsequent dehydration of the resultant alkylphenols (3) gave regioselectively the desired prenylphenols (4).Dehydration of alkylphenols (3f-h) gave chromans (7).
