Check Digit Verification of cas no

The CAS Registry Mumber 1374035-95-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,0,3 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1374035-95:
(9*1)+(8*3)+(7*7)+(6*4)+(5*0)+(4*3)+(3*5)+(2*9)+(1*5)=156
156 % 10 = 6
So 1374035-95-6 is a valid CAS Registry Number.

C2-symmetric recyclable organocatalyst for enantioselective Strecker reaction for the synthesis of α-amino acid and chiral diamine-an intermediate for APN inhibitor

Saravanan,Sadhukhan, Arghya,Khan, Noor-Ul H.,Kureshy, Rukhsana I.,Abdi, Sayed H. R.,Bajaj, Hari C.

, p. 4375 - 4384 (2012/06/30)

Recyclable chiral amide-based organocatalyst 5 efficiently catalyzed asymmetric Strecker reaction of various aromatic and aliphatic N-benzhydrylimines with ethyl cyanoformate as cyanide source at -10 °C to give a high yield (95%) of α-aminonitriles with excellent chiral induction (ee, up to 99%) with the added advantage of recyclability. Based on experimental observations a probable mechanism was proposed for this reaction. This protocol with catalyst 5 was extended for the synthesis of (R)-phenylalanine and pharmaceutically important drug intermediate (R)-3-phenylpropane-1,2-diamine in high yield with high enantioselectivity.
