89927-11-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89927-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,2 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89927-11:
(7*8)+(6*9)+(5*9)+(4*2)+(3*7)+(2*1)+(1*1)=187
187 % 10 = 7
So 89927-11-7 is a valid CAS Registry Number.
