620988-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 620988-42-3 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 620988-42:
(8*6)+(7*2)+(6*0)+(5*9)+(4*8)+(3*8)+(2*4)+(1*2)=173
173 % 10 = 3
So 620988-42-3 is a valid CAS Registry Number.
