130778-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130778-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,7 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130778-31:
(8*1)+(7*3)+(6*0)+(5*7)+(4*7)+(3*8)+(2*3)+(1*1)=123
123 % 10 = 3
So 130778-31-3 is a valid CAS Registry Number.
