73682-86-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73682-86-7 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 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73682-86:
(7*7)+(6*3)+(5*6)+(4*8)+(3*2)+(2*8)+(1*6)=157
157 % 10 = 7
So 73682-86-7 is a valid CAS Registry Number.
