135352-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135352-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,5 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135352-23:
(8*1)+(7*3)+(6*5)+(5*3)+(4*5)+(3*2)+(2*2)+(1*3)=107
107 % 10 = 7
So 135352-23-7 is a valid CAS Registry Number.
