Check Digit Verification of cas no
The CAS Registry Mumber 78302-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,0 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78302-39:
(7*7)+(6*8)+(5*3)+(4*0)+(3*2)+(2*3)+(1*9)=133
133 % 10 = 3
So 78302-39-3 is a valid CAS Registry Number.
