Check Digit Verification of cas no

The CAS Registry Mumber 1618673-08-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,6,7 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1618673-08:
(9*1)+(8*6)+(7*1)+(6*8)+(5*6)+(4*7)+(3*3)+(2*0)+(1*8)=187
187 % 10 = 7
So 1618673-08-7 is a valid CAS Registry Number.

Tertiary amide-based Knoevenagel-type reactions: A direct, general, and chemoselective approach to enaminones

Huang, Pei-Qiang,Ou, Wei,Xiao, Kai-Jiong,Wang, Ai-E.

supporting information, p. 8761 - 8763 (2014/07/22)

We report one-pot and chemoselective Knoevenagel-type reactions using highly stable amides and lactams as the electrophilic substrates. The method is based on the in situ activation of amide carbonyl with triflic anhydride and a subsequent reaction with carbanions generated in situ from carbonyl compounds. The amide-based method is an alternative to the versatile thioamide-based Eschenmoser sulfide contraction.
