879996-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 879996-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,9,9,9 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 879996-69:
(8*8)+(7*7)+(6*9)+(5*9)+(4*9)+(3*6)+(2*6)+(1*9)=287
287 % 10 = 7
So 879996-69-7 is a valid CAS Registry Number.
