1027143-47-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027143-47-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,1,4 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1027143-47:
(9*1)+(8*0)+(7*2)+(6*7)+(5*1)+(4*4)+(3*3)+(2*4)+(1*7)=110
110 % 10 = 0
So 1027143-47-0 is a valid CAS Registry Number.
