Check Digit Verification of cas no

The CAS Registry Mumber 74645-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,4 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74645-71:
(7*7)+(6*4)+(5*6)+(4*4)+(3*5)+(2*7)+(1*1)=149
149 % 10 = 9
So 74645-71-9 is a valid CAS Registry Number.

Photochemical Deoxygenation of an α-Ketol: The Dihydroflavonol-Flavanone Conversion

Westhuizen, Jan H. van der,Ferreira, Daneel,Roux, David G.

, p. 1003 - 1006 (1980)

Irradiation of optically pure 2,3-trans-3-hydroxyflavanones in anhydrous ethyl acetate leads directly to free phenolic flavanone analogues with complete retention of configuration at C(2).Similarly their methyl ethers give the corresponding flavanones and flavones.The reaction represents the photochemical equivalent of a reduction under Clemmensen conditions.
