Check Digit Verification of cas no
The CAS Registry Mumber 76969-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,6 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76969-20:
(7*7)+(6*6)+(5*9)+(4*6)+(3*9)+(2*2)+(1*0)=185
185 % 10 = 5
So 76969-20-5 is a valid CAS Registry Number.

A New Synthesis of DL-α,γ-Diamino Acids
Kidwai, Mazahir M.,Khan, Naseem H.
, p. 802 - 803 (2007/10/02)
A general method for the synthesis of α,γ-diamino acids from α,β-unsaturated aromatic acids is described.Treatment of α,β-unsaturated acids with phosphorus pentachloride and potassium cyanide followed by acid hydrolysis yields 3-arylidenepyruvic acids (2)
