1335284-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335284-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,2,8 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1335284-72:
(9*1)+(8*3)+(7*3)+(6*5)+(5*2)+(4*8)+(3*4)+(2*7)+(1*2)=154
154 % 10 = 4
So 1335284-72-4 is a valid CAS Registry Number.
