Check Digit Verification of cas no

The CAS Registry Mumber 891863-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,8,6 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 891863-23:
(8*8)+(7*9)+(6*1)+(5*8)+(4*6)+(3*3)+(2*2)+(1*3)=213
213 % 10 = 3
So 891863-23-3 is a valid CAS Registry Number.

A facile synthetic route to highly functionalized 2,4-pyrrolidinediones: A new base-catalyzed cyclization

Jin, Yu-Zi,Zhu Yin, Bing,Lee, Youn-Sik

, p. 357 - 368 (2007/10/03)

2,4-Pyrrolidinedione derivatives were synthesized in 67-85% yield in one-pot reaction via base-catalyzed cyclization of α-(arylvinylcarbonyl)-α′-(N-arylaminocarbonyl)ketene dithioacetals formed in situ by the reaction of a-acetyl-α′-(N-arylaminocarbonyl)k
