Check Digit Verification of cas no

The CAS Registry Mumber 278782-35-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,8,7,8 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 278782-35:
(8*2)+(7*7)+(6*8)+(5*7)+(4*8)+(3*2)+(2*3)+(1*5)=197
197 % 10 = 7
So 278782-35-7 is a valid CAS Registry Number.

Novel approach to the synthesis of aliphatic and aromatic α-keto acids

Balducci, Daniele,Conway, Philip A.,Sapuppo, Giulia,Müller-Bunz, Helge,Paradisi, Francesca

experimental part, p. 7374 - 7379 (2012/09/10)

A new practical and efficient synthesis of α-keto acids was accomplished starting from the synthon 1,4-diacetylpiperazine-2,5-dione. The synthesis encompasses both aromatic and aliphatic substrates proving to be versatile and innovative with excellent carbon economy and recycling of the glycine by-product.
