Check Digit Verification of cas no

The CAS Registry Mumber 1125557-70-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,5,5,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1125557-70:
(9*1)+(8*1)+(7*2)+(6*5)+(5*5)+(4*5)+(3*7)+(2*7)+(1*0)=141
141 % 10 = 1
So 1125557-70-1 is a valid CAS Registry Number.

Strecker-type reaction of nitrones using cyanohydrin

Sakai, Takahiro,Soeta, Takahiro,Inomata, Katsuhiko,Ukaji, Yutaka

scheme or table, p. 231 - 235 (2012/04/23)

Strecker-type reaction of nitrones using acetone cyanohydrin as a cyanide source was developed. By treating nitrones with acetone cyanohydrin in the presence of n-BuMgCl, transcyanation from the cyanohydrin to the nitrones smoothly proceeded in THF at 35 °C. The amount of n-BuMgCl could be reduced to 0.2 equiv to give the corresponding α-cyanohydroxylamines in up to 98% yields.
