153362-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153362-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,3,6 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153362-33:
(8*1)+(7*5)+(6*3)+(5*3)+(4*6)+(3*2)+(2*3)+(1*3)=115
115 % 10 = 5
So 153362-33-5 is a valid CAS Registry Number.
