898746-62-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 898746-62-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,7,4 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 898746-62:
(8*8)+(7*9)+(6*8)+(5*7)+(4*4)+(3*6)+(2*6)+(1*2)=258
258 % 10 = 8
So 898746-62-8 is a valid CAS Registry Number.
