167955-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 167955-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,9,5 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 167955-33:
(8*1)+(7*6)+(6*7)+(5*9)+(4*5)+(3*5)+(2*3)+(1*3)=181
181 % 10 = 1
So 167955-33-1 is a valid CAS Registry Number.
