Check Digit Verification of cas no

The CAS Registry Mumber 94975-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,9,7 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94975-33:
(7*9)+(6*4)+(5*9)+(4*7)+(3*5)+(2*3)+(1*3)=184
184 % 10 = 4
So 94975-33-4 is a valid CAS Registry Number.

AN EFFICIENT, REGIOSPECIFIC SYNTHESIS OF (+/-)-DAUNOMYCINONE

Kelly, T. Ross,Ananthasubramanian, L.,Borah, Kripinath,Gillard, John W.,Goerner, Richard N.,et al.

, p. 4569 - 4578 (1984)

The development of a general strategy for the control of regiochemistry in the Diels-Alder reactions of substituted naphthazarins is described.Application of this strategy to the synthesis of (+/-)-daunomycinone (2) employs two successive regiochemically controlled Diels-Alder reactions and leads to a ten-step, regiospecific synthesis of (+/-)-2 in 36percent overall yield (Scheme 4).
