848903-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 848903-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,8,9,0 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 848903-50:
(8*8)+(7*4)+(6*8)+(5*9)+(4*0)+(3*3)+(2*5)+(1*0)=204
204 % 10 = 4
So 848903-50-4 is a valid CAS Registry Number.
