159770-48-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159770-48-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,7 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 159770-48:
(8*1)+(7*5)+(6*9)+(5*7)+(4*7)+(3*0)+(2*4)+(1*8)=176
176 % 10 = 6
So 159770-48-6 is a valid CAS Registry Number.
