89982-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89982-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,8 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89982-90:
(7*8)+(6*9)+(5*9)+(4*8)+(3*2)+(2*9)+(1*0)=211
211 % 10 = 1
So 89982-90-1 is a valid CAS Registry Number.

Our previously developed synthesis of triaryl-substituted phosphaalkenes was adapted for the preparation of the phosphaalkenes 6a,b.In an attempt to prepare 6a along a direct, short route, a strongly contaminated product was obtained.However, the preparat
