637775-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637775-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,7,7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 637775-72:
(8*6)+(7*3)+(6*7)+(5*7)+(4*7)+(3*5)+(2*7)+(1*2)=205
205 % 10 = 5
So 637775-72-5 is a valid CAS Registry Number.
