136136-50-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136136-50-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,3 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136136-50:
(8*1)+(7*3)+(6*6)+(5*1)+(4*3)+(3*6)+(2*5)+(1*0)=110
110 % 10 = 0
So 136136-50-0 is a valid CAS Registry Number.
