Check Digit Verification of cas no
The CAS Registry Mumber 374073-54-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,4,0,7 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 374073-54:
(8*3)+(7*7)+(6*4)+(5*0)+(4*7)+(3*3)+(2*5)+(1*4)=148
148 % 10 = 8
So 374073-54-8 is a valid CAS Registry Number.

Synthesis of substituted indenes from isovanillin via claisen rearrangement and ring-closing metathesis
Huang, Keng-Shiang,Wang, Eng-Chi
, p. 383 - 391 (2014)
A new synthesis of substituted indenes was studied. Based on Claisen rearrangement,Wittig reaction and ring-closing metathesis (RCM), a series of substituted indenes was synthesized from isovanillin in good yields.
