Check Digit Verification of cas no

The CAS Registry Mumber 1671-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1671-78:
(6*1)+(5*6)+(4*7)+(3*1)+(2*7)+(1*8)=89
89 % 10 = 9
So 1671-78-9 is a valid CAS Registry Number.

α-Glucosidase inhibition of 6-hydroxyflavones. Part 3: Synthesis and evaluation of 2,3,4-trihydroxybenzoyl-containing flavonoid analogs and 6-aminoflavones as α-glucosidase inhibitors

Gao, Hong,Kawabata, Jun

, p. 1661 - 1671 (2007/10/03)

The SAR studies suggested that the C-ring of baicalein (1) was not necessary for the activity, and validated the importance of 2,3,4- trihydroxybenzoyl structure of 1. Thus, a series of 2,3,4-trihydroxybenzoyl- containing flavonoid analogs were investigat
