6727-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6727-63-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,2 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6727-63:
(6*6)+(5*7)+(4*2)+(3*7)+(2*6)+(1*3)=115
115 % 10 = 5
So 6727-63-5 is a valid CAS Registry Number.

Starting from GeCl4, the (hydroxymethyl)diorganylgermanes (CH3)2Ge(H)CH2OH and (C6H52Ge(H)CH2OH were prepared by a four-step synthesis in total yields of 15 and 32%, respectively (GeCl4 → Cl3GeCH2Cl → R2Ge(Cl)CH2Cl → R2Ge(OAc)CH2OAc → R2Ge(H)CH2OH; R CH3 or C6H5). The chemical reactivity of (CH3)2Ge(H)CH2OH and (C6H52Ge(H)CH2OH was found to be determined by their GeH and OH bonds.
