Check Digit Verification of cas no
The CAS Registry Mumber 136835-04-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,3 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136835-04:
(8*1)+(7*3)+(6*6)+(5*8)+(4*3)+(3*5)+(2*0)+(1*4)=136
136 % 10 = 6
So 136835-04-6 is a valid CAS Registry Number.
