135684-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135684-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,8 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135684-34:
(8*1)+(7*3)+(6*5)+(5*6)+(4*8)+(3*4)+(2*3)+(1*4)=143
143 % 10 = 3
So 135684-34-3 is a valid CAS Registry Number.
