Check Digit Verification of cas no

The CAS Registry Mumber 33355-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,5 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33355-58:
(7*3)+(6*3)+(5*3)+(4*5)+(3*5)+(2*5)+(1*8)=107
107 % 10 = 7
So 33355-58-7 is a valid CAS Registry Number.

CLEAVAGE OF PHOSPHOROUS-CARBON BONDS WITH SODIUM/NAPHTHALENE. FACILE PREPARATION OF UNSYMMETRICAL DIPHOSPHINES

Chou, Ta-Shue,Tsao, Chung-Huang,Hung, Su Chun

, p. 53 - 58 (2007/10/02)

Sodium/naphthalene was found to be a homogeneous, mild and selective reagent for the reductive cleavage of aryl-phosphorous bonds.Such cleavage reactions are very useful in the convenient synthesis of unsymmetrical diphosphines from commercially available and air-stable diphosphines.
