1335207-49-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335207-49-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,2,0 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1335207-49:
(9*1)+(8*3)+(7*3)+(6*5)+(5*2)+(4*0)+(3*7)+(2*4)+(1*9)=132
132 % 10 = 2
So 1335207-49-2 is a valid CAS Registry Number.
