98477-01-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98477-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,7 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98477-01:
(7*9)+(6*8)+(5*4)+(4*7)+(3*7)+(2*0)+(1*1)=181
181 % 10 = 1
So 98477-01-1 is a valid CAS Registry Number.
