Check Digit Verification of cas no

The CAS Registry Mumber 79057-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,0,5 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 79057-55:
(7*7)+(6*9)+(5*0)+(4*5)+(3*7)+(2*5)+(1*5)=159
159 % 10 = 9
So 79057-55-9 is a valid CAS Registry Number.

Biomimetic Approaches to Morphine Alkaloids. Total Synthesis of (+/-)-2-Hydroxycodeine and (+/-)-Noroxycodone

Schwartz, Martin A.,Zoda, Michael F.

, p. 4623 - 4625 (2007/10/02)

Oxidative coupling of a triphenolic hydroxynorreticuline substrate with VOCl3 affords the corresponding 2-hydroxynorsalutaridine derivative in good yield; the latter is readily converted to the title compounds via (+/-)-N-(ethoxycarbonyl)-2-hydroxynorthebaine.
