250675-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 250675-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,6,7 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 250675-83:
(8*2)+(7*5)+(6*0)+(5*6)+(4*7)+(3*5)+(2*8)+(1*3)=143
143 % 10 = 3
So 250675-83-3 is a valid CAS Registry Number.
