916756-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 916756-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,7,5 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 916756-25:
(8*9)+(7*1)+(6*6)+(5*7)+(4*5)+(3*6)+(2*2)+(1*5)=197
197 % 10 = 7
So 916756-25-7 is a valid CAS Registry Number.

Synthesis of phosphane oxide bridged bis- and triscatechol derivatives
Albrecht, Markus,Song, Yun
, p. 3037 - 3042 (2008/02/08)
Linear biscatechols and triangular triscatechols possessing spacers containing phosphane oxide were synthesized. For this, the central phosphorus was introduced by the reaction of active organometallic intermediates with either dichlorophenylphosphane or
