850254-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850254-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,2,5 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 850254-52:
(8*8)+(7*5)+(6*0)+(5*2)+(4*5)+(3*4)+(2*5)+(1*2)=153
153 % 10 = 3
So 850254-52-3 is a valid CAS Registry Number.
