Check Digit Verification of cas no

The CAS Registry Mumber 138849-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,4 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138849-70:
(8*1)+(7*3)+(6*8)+(5*8)+(4*4)+(3*9)+(2*7)+(1*0)=174
174 % 10 = 4
So 138849-70-4 is a valid CAS Registry Number.

Yoshida, Hiroshi,Aoyama, Masanori,Utsumi, Fumitaka,Ogata, Tsuyoshi,Matsumoto, Kiyoshi

, p. 3476 - 3478 (2007/10/02)

The reaction of 1,2-diphenyl- and 1-methyl-2-phenyl-3,3-dichloro- or dibromocyclopropenes with trialkylphosphites, dialkyl phenylphosphonites, and alkyl diphenylphosphinites afforded cyclopropenes with 3,3-diorganophosphorous substituents in moderate yiel
