86737-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86737-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,7,3 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 86737-52:
(7*8)+(6*6)+(5*7)+(4*3)+(3*7)+(2*5)+(1*2)=172
172 % 10 = 2
So 86737-52-2 is a valid CAS Registry Number.
