NotclassifiedCheck Digit Verification of cas no
The CAS Registry Mumber 28706-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,0 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.Calculate Digit Verification of CAS Registry Number 28706-25:
(7*2)+(6*8)+(5*7)+(4*0)+(3*6)+(2*2)+(1*5)=124
124 % 10 = 4
So 28706-25-4 is a valid CAS Registry Number.
