Check Digit Verification of cas no
The CAS Registry Mumber 130769-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,6 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130769-89:
(8*1)+(7*3)+(6*0)+(5*7)+(4*6)+(3*9)+(2*8)+(1*9)=140
140 % 10 = 0
So 130769-89-0 is a valid CAS Registry Number.
