Check Digit Verification of cas no
The CAS Registry Mumber 136000-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,0,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136000-25:
(8*1)+(7*3)+(6*6)+(5*0)+(4*0)+(3*0)+(2*2)+(1*5)=74
74 % 10 = 4
So 136000-25-4 is a valid CAS Registry Number.
