Check Digit Verification of cas no

The CAS Registry Mumber 108583-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,5,8 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108583-47:
(8*1)+(7*0)+(6*8)+(5*5)+(4*8)+(3*3)+(2*4)+(1*7)=137
137 % 10 = 7
So 108583-47-7 is a valid CAS Registry Number.

Solvent-free synthesis of cyanohydrin derivatives catalysed by triethylamine

Baeza, Alejandro,Najera, Carmen,Retamosa, Ma. De Gracia,Sansano, Jose M.

, p. 2787 - 2797 (2007/10/03)

A very simple one-step environmentally friendly procedure for the synthesis of O-substituted cyanohydrins from aldehydes and ketones, in the absence of solvent, employing minimum amounts of the corresponding cyanides has been optimised. Aldehydes react more rapidly than ketones using triethylamine as catalyst offering in both cases almost quantitative yields of the corresponding O-trimethylsilyl, O-methoxycarbonyl, O-benzoyl and O-acetyl cyanohydrins. Georg Thieme Verlag Stuttgart.
