1031436-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1031436-63-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,4,3 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1031436-63:
(9*1)+(8*0)+(7*3)+(6*1)+(5*4)+(4*3)+(3*6)+(2*6)+(1*3)=101
101 % 10 = 1
So 1031436-63-1 is a valid CAS Registry Number.
