134936-16-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134936-16-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134936-16:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*6)+(2*1)+(1*6)=136
136 % 10 = 6
So 134936-16-6 is a valid CAS Registry Number.
