158396-15-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158396-15-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,3,9 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158396-15:
(8*1)+(7*5)+(6*8)+(5*3)+(4*9)+(3*6)+(2*1)+(1*5)=167
167 % 10 = 7
So 158396-15-7 is a valid CAS Registry Number.
