135681-35-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135681-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,8 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135681-35:
(8*1)+(7*3)+(6*5)+(5*6)+(4*8)+(3*1)+(2*3)+(1*5)=135
135 % 10 = 5
So 135681-35-5 is a valid CAS Registry Number.
