Check Digit Verification of cas no

The CAS Registry Mumber 176749-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,7,4 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 176749-85:
(8*1)+(7*7)+(6*6)+(5*7)+(4*4)+(3*9)+(2*8)+(1*5)=192
192 % 10 = 2
So 176749-85-2 is a valid CAS Registry Number.

Synthesis of (1R)-(+)-nopinone- and (1S)-(-)-verbenone-derived chiral annulated indenes via electrocyclic reactions

Liu, Chao,Sowa Jr., John R.

, p. 7241 - 7244 (1996)

Two new chiral annulated indene derivatives have been stereoselectively synthesized via acid-catalyzed electrocyclic reactions from naturally occurring homochiral precursors (1R)-(+)-nopinone and (1S)-(-)-verbenone.
