(8*1)+(7*3)+(6*8)+(5*8)+(4*9)+(3*9)+(2*9)+(1*1)=199
199 % 10 = 9
So 138899-91-9 is a valid CAS Registry Number.

Syntheses of W(PhCCPh)3(η1-PPh2CH2PPh2) and W(PhCCPh)3(PPh3) from W(PhCCPh)3(NCCH3)

Yeh, Wen-Yann,Ting, Che-Sheng,Chih, Chu-fang

, p. 257 - 262 (1992)

W(PhCPh)3(NCCH3) has been synthesized by treating W(PhCCPh)3(CO) with Me3NO in acetonitrile solution.Reactions of W(PhCCPh)3(NCCH3) with (PPh2)2CH2 and PPh3 afford W(PhCCPh)3(η1-PPh2CH2PPh2) and W(PhCCPh)3(PPh3), respectively.
