1027178-53-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027178-53-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,1,7 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027178-53:
(9*1)+(8*0)+(7*2)+(6*7)+(5*1)+(4*7)+(3*8)+(2*5)+(1*3)=135
135 % 10 = 5
So 1027178-53-5 is a valid CAS Registry Number.
