878626-88-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 878626-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,6,2 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 878626-88:
(8*8)+(7*7)+(6*8)+(5*6)+(4*2)+(3*6)+(2*8)+(1*8)=241
241 % 10 = 1
So 878626-88-1 is a valid CAS Registry Number.
