200639-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200639-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,6,3 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 200639-75:
(8*2)+(7*0)+(6*0)+(5*6)+(4*3)+(3*9)+(2*7)+(1*5)=104
104 % 10 = 4
So 200639-75-4 is a valid CAS Registry Number.
