200879-63-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200879-63-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,8,7 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 200879-63:
(8*2)+(7*0)+(6*0)+(5*8)+(4*7)+(3*9)+(2*6)+(1*3)=126
126 % 10 = 6
So 200879-63-6 is a valid CAS Registry Number.
