Check Digit Verification of cas no
The CAS Registry Mumber 130999-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,9 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130999-12:
(8*1)+(7*3)+(6*0)+(5*9)+(4*9)+(3*9)+(2*1)+(1*2)=141
141 % 10 = 1
So 130999-12-1 is a valid CAS Registry Number.
