298689-33-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 298689-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,8,6,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 298689-33:
(8*2)+(7*9)+(6*8)+(5*6)+(4*8)+(3*9)+(2*3)+(1*3)=225
225 % 10 = 5
So 298689-33-5 is a valid CAS Registry Number.

α-Aminonitrile was an important building block in natural products and key intermedia in organic chemistry. Herein, the direct amination of cyanohydrins with the partner of ammonia to synthesis N-unprotected α-aminonitriles is developed. The reaction proceeds via titanium-catalyzed cyano-borrowing reaction, which features high atom economy and simple operation. A broad range of ketone or aldehyde cyanohydrins was tolerated with ammonia, and the N-unprotected α-aminonitriles were synthesis with moderate to high yields under mild reaction conditions.
