Check Digit Verification of cas no

The CAS Registry Mumber 81504-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,0 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81504-95:
(7*8)+(6*1)+(5*5)+(4*0)+(3*4)+(2*9)+(1*5)=122
122 % 10 = 2
So 81504-95-2 is a valid CAS Registry Number.

Preparation of (-)-(7R)-7-Acetyl-7-hydroxy-4,4-dimethoxy-5,6,7,8-tetrahydronaphthalen-1(4H)-one, a Chiral AB-Synthon for Anthracycline Synthesis

Warrener, Ronald N.,Gee, Paul S.,Russell, Richard A.

, p. 1100 - 1101 (2007/10/02)

The (-)-(R)-dienone (13) was prepared in 10 steps from the known 8-hydroxy-5-methoxy-2,3-dihydronaphthalen-1(4H)-one (2), and the chirality at C(7) in (13) corresponds to that found at C(9) in the naturally occurring anthracyclines related to daunomycin.
