Check Digit Verification of cas no
The CAS Registry Mumber 130156-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,5 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130156-86:
(8*1)+(7*3)+(6*0)+(5*1)+(4*5)+(3*6)+(2*8)+(1*6)=94
94 % 10 = 4
So 130156-86-4 is a valid CAS Registry Number.
