1287221-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1287221-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,2,2 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1287221-47:
(9*1)+(8*2)+(7*8)+(6*7)+(5*2)+(4*2)+(3*1)+(2*4)+(1*7)=159
159 % 10 = 9
So 1287221-47-9 is a valid CAS Registry Number.
