193018-00-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193018-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,0,1 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 193018-00:
(8*1)+(7*9)+(6*3)+(5*0)+(4*1)+(3*8)+(2*0)+(1*0)=117
117 % 10 = 7
So 193018-00-7 is a valid CAS Registry Number.

Convenient synthesis of W(≡CR)X3(dme) compounds from W(≡CR)(OBut)3 triple-bond metathesis products
Stevenson, Margaret A.,Hopkins, Michael D.
, p. 3572 - 3573 (2008/10/08)
Tungsten-alkylidyne complexes of the type W(≡CR)X3(dme) (R = But, Prn, Ph; X = Cl, Br; dme = 1,2-dimethoxyethane) are prepared in 77-87% yields from reactions between W(≡CR)(OBut)3 and BX3
