Check Digit Verification of cas no

The CAS Registry Mumber 1147869-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,7,8,6 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1147869-71:
(9*1)+(8*1)+(7*4)+(6*7)+(5*8)+(4*6)+(3*9)+(2*7)+(1*1)=193
193 % 10 = 3
So 1147869-71-3 is a valid CAS Registry Number.

Water-triggered, counter-anion-controlled, and silver-phosphines complex-catalyzed stereoselective cascade alkynylation/cyclization of terminal alkynes with salicylaldehydes

Yu, Min,Skouta, Rachid,Zhou, Lei,Jiang, Huan-Feng,Yao, Xiaoquan,Li, Chao-Jun

, p. 3378 - 3383 (2009)

A highly efficient alkynylation-cyclization of terminal alkynes with salicylaldehydes leading to substituted 2,3-dihydrobenzofuran-3-ol derivatives was developed by using Cy3P-silver complex as catalyst in water. Counter anions in the silver co
