1143019-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1143019-74-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,3,0,1 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1143019-74:
(9*1)+(8*1)+(7*4)+(6*3)+(5*0)+(4*1)+(3*9)+(2*7)+(1*4)=112
112 % 10 = 2
So 1143019-74-2 is a valid CAS Registry Number.
