620970-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 620970-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,7 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 620970-67:
(8*6)+(7*2)+(6*0)+(5*9)+(4*7)+(3*0)+(2*6)+(1*7)=154
154 % 10 = 4
So 620970-67-4 is a valid CAS Registry Number.
