89229-77-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89229-77-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,2 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89229-77:
(7*8)+(6*9)+(5*2)+(4*2)+(3*9)+(2*7)+(1*7)=176
176 % 10 = 6
So 89229-77-6 is a valid CAS Registry Number.
