Check Digit Verification of cas no

The CAS Registry Mumber 1309976-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,9,7 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1309976-99:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*7)+(3*6)+(2*9)+(1*9)=205
205 % 10 = 5
So 1309976-99-5 is a valid CAS Registry Number.

Synthesis of α-Arylcarboxylic acid amides from silyl enol ether via migratory Amidation with 2-azido-1,3-dimethylimidazolinium hexafluorophosphate

Kitamura, Mitsuru,Murakami, Kento,Shiratake, Yuichiro,Okauchi, Tatsuo

, p. 691 - 693 (2013/07/26)

α-Arylcarboxylic acid amides were synthesized by reacting silyl enol ethers of aryl ketones and 2-azido-1,3-dimethylimidazolinium hexafluorophosphate (ADMP,1). Silyl enol ethers react with ADMP 1 to give N-(α-arylacyl) guanidines via the migration of aryl groups in enol ethers. The products were transformed to the corresponding α-aryl acetamides by treating with LiAlH4.
