145527-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145527-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,5,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145527-20:
(8*1)+(7*4)+(6*5)+(5*5)+(4*2)+(3*7)+(2*2)+(1*0)=124
124 % 10 = 4
So 145527-20-4 is a valid CAS Registry Number.
