Check Digit Verification of cas no
The CAS Registry Mumber 7782-85-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7782-85:
(6*7)+(5*7)+(4*8)+(3*2)+(2*8)+(1*5)=136
136 % 10 = 6
So 7782-85-6 is a valid CAS Registry Number.
