89762-55-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89762-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,6 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89762-55:
(7*8)+(6*9)+(5*7)+(4*6)+(3*2)+(2*5)+(1*5)=190
190 % 10 = 0
So 89762-55-0 is a valid CAS Registry Number.
