Check Digit Verification of cas no

The CAS Registry Mumber 81328-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,2 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81328-70:
(7*8)+(6*1)+(5*3)+(4*2)+(3*8)+(2*7)+(1*0)=123
123 % 10 = 3
So 81328-70-3 is a valid CAS Registry Number.

Synthesis of dl-3-Hydroxycuparene by a Claisen Rearrangement of Allyl Aryl Ether

Inouye, Yoshinobu,Inomata, Satoru,Ishihara, Yasumasa,Kakisawa, Hiroshi

, p. 208 - 211 (2007/10/02)

The Claisen rearrangement of 1-methyl-2-cyclopentene in N,N-dimethylformamide gave 5-methyl-2-(1-methyl-2-methylenecyclopentyl)phenol (5) via its trimethylsilyl ether. The methylation of 5, followed by a Simmons-Smith reaction and by the catalytic hydrogenolysis, afforded 3-hydroxycuparene.
