Check Digit Verification of cas no
The CAS Registry Mumber 78887-48-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,8 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78887-48:
(7*7)+(6*8)+(5*8)+(4*8)+(3*7)+(2*4)+(1*8)=206
206 % 10 = 6
So 78887-48-6 is a valid CAS Registry Number.
