50299-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50299-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,2,9 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 50299-98:
(7*5)+(6*0)+(5*2)+(4*9)+(3*9)+(2*9)+(1*8)=134
134 % 10 = 4
So 50299-98-4 is a valid CAS Registry Number.
