92012-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92012-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,1 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92012-23:
(7*9)+(6*2)+(5*0)+(4*1)+(3*2)+(2*2)+(1*3)=92
92 % 10 = 2
So 92012-23-2 is a valid CAS Registry Number.
