132870-06-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132870-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,7 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132870-06:
(8*1)+(7*3)+(6*2)+(5*8)+(4*7)+(3*0)+(2*0)+(1*6)=115
115 % 10 = 5
So 132870-06-5 is a valid CAS Registry Number.

A novel synthesis of α-aminoaldehydes from glyoxal monoacetal
Katritzky,Borowiecka,Fan
, p. 1173 - 1176 (2007/10/02)
Primary and secondary amines condense with benzotriazole and glyoxal monoacetal to give N-substituted 1-(benzotriazolyl)-2,2-diethoxyethylamines 4, which with Grignard reagents readily yield the corresponding 2-aminoalkanal diethylacetal 5. These are easily hydrolyzed to produce α-aminoaldehydes 6.
