1027254-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027254-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,2,5 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1027254-52:
(9*1)+(8*0)+(7*2)+(6*7)+(5*2)+(4*5)+(3*4)+(2*5)+(1*2)=119
119 % 10 = 9
So 1027254-52-9 is a valid CAS Registry Number.
