83567-98-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83567-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,6 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83567-98:
(7*8)+(6*3)+(5*5)+(4*6)+(3*7)+(2*9)+(1*8)=170
170 % 10 = 0
So 83567-98-0 is a valid CAS Registry Number.
