893657-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 893657-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,6,5 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 893657-08:
(8*8)+(7*9)+(6*3)+(5*6)+(4*5)+(3*7)+(2*0)+(1*8)=224
224 % 10 = 4
So 893657-08-4 is a valid CAS Registry Number.
