197240-64-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197240-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,2,4 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 197240-64:
(8*1)+(7*9)+(6*7)+(5*2)+(4*4)+(3*0)+(2*6)+(1*4)=155
155 % 10 = 5
So 197240-64-5 is a valid CAS Registry Number.
