Check Digit Verification of cas no

The CAS Registry Mumber 212389-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,3,8 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 212389-12:
(8*2)+(7*1)+(6*2)+(5*3)+(4*8)+(3*9)+(2*1)+(1*2)=113
113 % 10 = 3
So 212389-12-3 is a valid CAS Registry Number.

, p. 982 - 986 (1998)

The synthesis of known (3-6) and new (7-10 and 14-22) coumarins in the seselin and xanthyletin series is described. The cytotoxic activity of compounds 3-22 was carried out in vitro on L-1210 cells. The most active compounds were 9, 16, 18, and 20 in the seselin series and 10, 17, and 19 in the xanthyletin series. Structure-activity relationships are discussed.
