1123311-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1123311-72-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,3,1 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1123311-72:
(9*1)+(8*1)+(7*2)+(6*3)+(5*3)+(4*1)+(3*1)+(2*7)+(1*2)=87
87 % 10 = 7
So 1123311-72-7 is a valid CAS Registry Number.
