1620210-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620210-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,2,1 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1620210-75:
(9*1)+(8*6)+(7*2)+(6*0)+(5*2)+(4*1)+(3*0)+(2*7)+(1*5)=104
104 % 10 = 4
So 1620210-75-4 is a valid CAS Registry Number.
