Check Digit Verification of cas no

The CAS Registry Mumber 1428263-71-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,2,6 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1428263-71:
(9*1)+(8*4)+(7*2)+(6*8)+(5*2)+(4*6)+(3*3)+(2*7)+(1*1)=161
161 % 10 = 1
So 1428263-71-1 is a valid CAS Registry Number.

Willgerodt-Kindler reaction of arylglyoxals with amines and sulfur in aqueous media: A simple and efficient synthesis of -ketothioamides

Eftekhari-Sis, Bagher,Vahdati-Khajeh, Saleh,Amini, S. Motahhareh,Zirak, Maryam,Saraei, Mahnaz

, p. 464 - 473 (2013)

A simple and efficient method for the synthesis of -ketothioamides via the Willgerodt-Kindler reaction is developed. Reactions were carried out between arylglyoxal hydrates, amines and elemental sulfur in water at 80°C to afford corresponding -ketothioamides in good to high yields in a short reaction time.
