27285-12-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27285-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,2,8 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 27285-12:
(7*2)+(6*7)+(5*2)+(4*8)+(3*5)+(2*1)+(1*2)=117
117 % 10 = 7
So 27285-12-7 is a valid CAS Registry Number.
