Check Digit Verification of cas no

The CAS Registry Mumber 125346-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,3,4 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125346-79:
(8*1)+(7*2)+(6*5)+(5*3)+(4*4)+(3*6)+(2*7)+(1*9)=124
124 % 10 = 4
So 125346-79-4 is a valid CAS Registry Number.

Synthesis of tetrakis(2,6-diisopropylphenyl)digermene and its reductive cleavage to the corresponding digermenyllithium-(DME) complex

Park, Jaiwook,Batcheller, Scott A.,Masamune, Satoru

, p. 39 - 46 (1989)

Tetrakis(2,6-diisopropylphenyl)digermene is synthesized directly from bis(2,6-diisopropylphenyl)dichlorogermane by reductive coupling with lithium naphthalenide in dimethoxyethane (DME).Its structural integrity (double bond) is retained in solution and addition of methanol leads to 1-methoxy-1,1,2,2-tetrakis(2,6-diisopropylphenyl)digermane.Treatment of the digrermene with further equivalents of lithium naphthalenide in DME provided a novel digermenyllithium species.
