137853-35-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137853-35-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,5 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137853-35:
(8*1)+(7*3)+(6*7)+(5*8)+(4*5)+(3*3)+(2*3)+(1*5)=151
151 % 10 = 1
So 137853-35-1 is a valid CAS Registry Number.
