135924-15-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135924-15-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,2 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135924-15:
(8*1)+(7*3)+(6*5)+(5*9)+(4*2)+(3*4)+(2*1)+(1*5)=131
131 % 10 = 1
So 135924-15-1 is a valid CAS Registry Number.
