160621-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160621-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,6,2 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 160621-45:
(8*1)+(7*6)+(6*0)+(5*6)+(4*2)+(3*1)+(2*4)+(1*5)=104
104 % 10 = 4
So 160621-45-4 is a valid CAS Registry Number.
