Check Digit Verification of cas no

The CAS Registry Mumber 68634-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,6,3 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68634-19:
(7*6)+(6*8)+(5*6)+(4*3)+(3*4)+(2*1)+(1*9)=155
155 % 10 = 5
So 68634-19-5 is a valid CAS Registry Number.

Demethylxanthohumol: Isolation from Hops and Cyclisation to Flavanons

Haensel, Rudolf,Schulz, Jutta

, p. 37 - 40 (1988)

Demethylxanthohumol (1) was isolated together with xanthohumol (2) from freshly harvested strobili of hops (humulus lupulus L.).Structure proof of 1 is based on spectroscopic data and on the transformation of 1 and 2 into trimethylxanthohumol (3).Treatmen
