Check Digit Verification of cas no
The CAS Registry Mumber 130278-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,7 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130278-26:
(8*1)+(7*3)+(6*0)+(5*2)+(4*7)+(3*8)+(2*2)+(1*6)=101
101 % 10 = 1
So 130278-26-1 is a valid CAS Registry Number.
