825594-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 825594-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,5,5,9 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 825594-50:
(8*8)+(7*2)+(6*5)+(5*5)+(4*9)+(3*4)+(2*5)+(1*0)=191
191 % 10 = 1
So 825594-50-1 is a valid CAS Registry Number.
