Check Digit Verification of cas no
The CAS Registry Mumber 78889-15-3 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 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78889-15:
(7*7)+(6*8)+(5*8)+(4*8)+(3*9)+(2*1)+(1*5)=203
203 % 10 = 3
