73688-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73688-67-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,8 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73688-67:
(7*7)+(6*3)+(5*6)+(4*8)+(3*8)+(2*6)+(1*7)=172
172 % 10 = 2
So 73688-67-2 is a valid CAS Registry Number.
