396728-98-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 396728-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,6,7,2 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 396728-98:
(8*3)+(7*9)+(6*6)+(5*7)+(4*2)+(3*8)+(2*9)+(1*8)=216
216 % 10 = 6
So 396728-98-6 is a valid CAS Registry Number.
