112892-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112892-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112892-39:
(8*1)+(7*1)+(6*2)+(5*8)+(4*9)+(3*2)+(2*3)+(1*9)=124
124 % 10 = 4
So 112892-39-4 is a valid CAS Registry Number.
