419562-75-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 419562-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,9,5,6 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 419562-75:
(8*4)+(7*1)+(6*9)+(5*5)+(4*6)+(3*2)+(2*7)+(1*5)=167
167 % 10 = 7
So 419562-75-7 is a valid CAS Registry Number.
