5Check Digit Verification of cas no
The CAS Registry Mumber 6527-65-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,2 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 6527-65:
(6*6)+(5*5)+(4*2)+(3*7)+(2*6)+(1*5)=107
107 % 10 = 7
So 6527-65-7 is a valid CAS Registry Number.
