130693-51-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130693-51-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,9 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130693-51:
(8*1)+(7*3)+(6*0)+(5*6)+(4*9)+(3*3)+(2*5)+(1*1)=115
115 % 10 = 5
So 130693-51-5 is a valid CAS Registry Number.
