1245744-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1245744-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,7,4 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1245744-65:
(9*1)+(8*2)+(7*4)+(6*5)+(5*7)+(4*4)+(3*4)+(2*6)+(1*5)=163
163 % 10 = 3
So 1245744-65-3 is a valid CAS Registry Number.
