1141934-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1141934-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,9,3 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1141934-87:
(9*1)+(8*1)+(7*4)+(6*1)+(5*9)+(4*3)+(3*4)+(2*8)+(1*7)=143
143 % 10 = 3
So 1141934-87-3 is a valid CAS Registry Number.
