Check Digit Verification of cas no
The CAS Registry Mumber 78697-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,9 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78697-41:
(7*7)+(6*8)+(5*6)+(4*9)+(3*7)+(2*4)+(1*1)=193
193 % 10 = 3
So 78697-41-3 is a valid CAS Registry Number.
