1303951-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1303951-55-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,3,9,5 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1303951-55:
(9*1)+(8*3)+(7*0)+(6*3)+(5*9)+(4*5)+(3*1)+(2*5)+(1*5)=134
134 % 10 = 4
So 1303951-55-4 is a valid CAS Registry Number.
