Check Digit Verification of cas no
The CAS Registry Mumber 1779-17-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,7 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1779-17:
(6*1)+(5*7)+(4*7)+(3*9)+(2*1)+(1*7)=105
105 % 10 = 5
