1233181-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1233181-68-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,1,8 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233181-68:
(9*1)+(8*2)+(7*3)+(6*3)+(5*1)+(4*8)+(3*1)+(2*6)+(1*8)=124
124 % 10 = 4
So 1233181-68-4 is a valid CAS Registry Number.
