Check Digit Verification of cas no
The CAS Registry Mumber 215951-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,9,5 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 215951-98:
(8*2)+(7*1)+(6*5)+(5*9)+(4*5)+(3*1)+(2*9)+(1*8)=147
147 % 10 = 7
So 215951-98-7 is a valid CAS Registry Number.

(Chemical Equation Presented) Bis(phosphine)boronium salts 3a-c were designed and prepared as key building blocks for the synthesis of highly congested diphosphinobenzenes. The preparation of sterically hindered ortho-phenylene-bridged diphosphines 1a-c was achieved by the reaction of the bis(phosphine)boronium salts 3a-c with difluorobenzenechromium complex 2 and subsequent removal of the BH2 group. The steric nature of diphosphine 1a was revealed in single-crystal X-ray analysis of its Rh complex.
