1313867-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313867-67-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,8,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1313867-67:
(9*1)+(8*3)+(7*1)+(6*3)+(5*8)+(4*6)+(3*7)+(2*6)+(1*7)=162
162 % 10 = 2
So 1313867-67-2 is a valid CAS Registry Number.
