1254223-73-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1254223-73-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,2,2 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1254223-73:
(9*1)+(8*2)+(7*5)+(6*4)+(5*2)+(4*2)+(3*3)+(2*7)+(1*3)=128
128 % 10 = 8
So 1254223-73-8 is a valid CAS Registry Number.
