620988-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 620988-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,8 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 620988-43:
(8*6)+(7*2)+(6*0)+(5*9)+(4*8)+(3*8)+(2*4)+(1*3)=174
174 % 10 = 4
So 620988-43-4 is a valid CAS Registry Number.
