89030-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89030-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,3 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89030-50:
(7*8)+(6*9)+(5*0)+(4*3)+(3*0)+(2*5)+(1*0)=132
132 % 10 = 2
So 89030-50-2 is a valid CAS Registry Number.
