203570-62-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 203570-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,5,7 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 203570-62:
(8*2)+(7*0)+(6*3)+(5*5)+(4*7)+(3*0)+(2*6)+(1*2)=101
101 % 10 = 1
So 203570-62-1 is a valid CAS Registry Number.
