92897-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92897-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,9 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92897-33:
(7*9)+(6*2)+(5*8)+(4*9)+(3*7)+(2*3)+(1*3)=181
181 % 10 = 1
So 92897-33-1 is a valid CAS Registry Number.
