92172-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92172-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,7 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92172-68:
(7*9)+(6*2)+(5*1)+(4*7)+(3*2)+(2*6)+(1*8)=134
134 % 10 = 4
So 92172-68-4 is a valid CAS Registry Number.
