Check Digit Verification of cas no

The CAS Registry Mumber 74785-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,8 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74785-90:
(7*7)+(6*4)+(5*7)+(4*8)+(3*5)+(2*9)+(1*0)=173
173 % 10 = 3
So 74785-90-3 is a valid CAS Registry Number.

Stereoselective Synthesis of Substituted Tetrahydropyrans and Isochromans by Cyclization of Phenylseleno Alcohols

Temperini, Andrea,Barattucci, Anna,Bonaccorsi, Paola Maria,Rosati, Ornelio,Minuti, Lucio

, p. 8102 - 8112 (2015)

A selenium-mediated strategy for the stereoselective synthesis of substituted tetrahydropyrans and isochromans has been developed starting from δ-phenylseleno ketones. After enantioselective reduction, the chiral nonracemic phenylseleno alcohols were oxidized to the corresponding selenones, which underwent an effcient 6-exo-tet ring-closure reaction.
