135735-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135735-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,3 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135735-08:
(8*1)+(7*3)+(6*5)+(5*7)+(4*3)+(3*5)+(2*0)+(1*8)=129
129 % 10 = 9
So 135735-08-9 is a valid CAS Registry Number.
