152168-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152168-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,6 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 152168-72:
(8*1)+(7*5)+(6*2)+(5*1)+(4*6)+(3*8)+(2*7)+(1*2)=124
124 % 10 = 4
So 152168-72-4 is a valid CAS Registry Number.
