7626-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7626-81-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,2 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7626-81:
(6*7)+(5*6)+(4*2)+(3*6)+(2*8)+(1*1)=115
115 % 10 = 5
So 7626-81-5 is a valid CAS Registry Number.
