Check Digit Verification of cas no

The CAS Registry Mumber 1243580-67-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,5,8 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1243580-67:
(9*1)+(8*2)+(7*4)+(6*3)+(5*5)+(4*8)+(3*0)+(2*6)+(1*7)=147
147 % 10 = 7

Meshram,Ramesh,Santosh Kumar,Chennakesava Reddy

, p. 4313 - 4316 (2010)

The catalyst-free one-pot synthesis of quinoxaline-2-carboxylate is reported by the reaction of α-halo-β-ketoesters with 1,2-diamines using an ionic liquid as an environmentally benign solvent. The recovered ionic liquid was reused for four to five cycles
