Check Digit Verification of cas no
The CAS Registry Mumber 74708-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,0 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74708-36:
(7*7)+(6*4)+(5*7)+(4*0)+(3*8)+(2*3)+(1*6)=144
144 % 10 = 4
So 74708-36-4 is a valid CAS Registry Number.

Shi, XueGong,Gu, WenXin,Wu, TongXing,Pan, XinFu
, p. 2625 - 2628 (2007/10/03)
Isoamericanol A 4 and isoamericanin A 5 have been synthesized via a novel effective route. 3,4-dihydroxycinnamic alcohol 3 is self-coupled to afford isoamericanol A 4 which is oxidized to obtain isoamericanin A 5.
