Check Digit Verification of cas no
The CAS Registry Mumber 706816-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,6,8,1 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 706816-89:
(8*7)+(7*0)+(6*6)+(5*8)+(4*1)+(3*6)+(2*8)+(1*9)=179
179 % 10 = 9
So 706816-89-9 is a valid CAS Registry Number.
